'89 3/4T 'burb front-end swap to '66 C20
 

I look at the restoration of my truck as two main parts: Mechanical & Aesthetics. The mechanical part being everything that's under the body & bed boards while the aesthetics are well, the rest of the stuff that makes the truck pretty.

My plan is to complete the mechanical resto first, then worry about the paint & body part. The way I'm going about this is a little different, because I drive my truck every day.

Most normal people would buy their project truck, make a budget, and either buy all of the parts they're going to need up front, or tear down their truck first, then purchase the parts. Then sand blast, clean up, patch up, paint and re-assemble with new parts, engine, trans, drive line, diff, wheels exhaust cab, front clip, electrical, bed & bed wood - done! (not necessarily in that order)

My approach is different for 2 reasons:

1. I don't have shop big enough to store a stripped down frame off truck for a year or so until I can finish it.

2. I drive my truck every day.

The modified plan goes something like this:

• Come up with a budget
• Buy most of the parts up front collect duplicate body parts to either restore, or to take the place of the originals that are restorable so I can continue to drive my truck.
• Break off the resto into bite sized chunks that can be completed in a reasonable amount of time
• Complete the mechanical resto
• Paint the restored body panels separately with the same # of coats, with the gun at the same distance using the same mix ratio
• Pull the truck in all at once tear down to frame & drive train reassemble with restored cab, bed & body panels install new wiring & electrical, glass and cab interior

I've broken the mechanical part down into 3 phases:

• Drive train - engine, fuel & exhaust systems & transmission
• Front-end - front suspension, steering & front brakes
• Rear end - differential, rear suspension, rear brakes, saddle tanks, wheels, tires & tow hitch

The Aesthetics part doesn't really break down into phases because I can do all of the work off-vehicle (with the exception of the bed because I don't have a spare one of those) and assemble it all at the final tear down.

Well it's been a long time coming, but with the engine, exhaust and transmission completed like I wanted it, the time is finally here to start phase 2 of the mechanical "restoration" of my truck!

My plan to upgrade my steering & brakes was to swap out a complete front suspension from a later model truck - cross member & all. Not only does this fit my modular approach to minimize down time, but it also makes it easier to avoid geometry issues and replacement parts later on. I can also sell my vintage "power assisted" steering parts at the swap meet as a complete package.

Some time ago (about 4 years ago) I purchased a front end out of an '89 3/4 ton Suburban:

After a not so brief intermission, (2 years recovering from a near fatal aortic aneurysm) I was finally able to complete the re-build:

http://www.chevytalk.org/fusionbb/fb...120881-002.JPGhttp://www.chevytalk.org/fusionbb/fb...120886-003.JPG

Here’s most of the parts I'll need to complete the upgrade:

http://www.chevytalk.org/fusionbb/fb...120914-005.JPG

New calipers & pads, new outer tie rod ends, new dual mastercyl/brake booster kit adapted for a '66 Chevy truck, a re-manufactured p/s box from the '89 3/4 ton 'burb, new sway bar bushings, brackets, good used pitman arm (89 burb), good used inner tie rod ends, good used idler arm/center link and good used sway bar brackets for front cross-member.

The huge 1-1/4" sway bar, the re-man p/s pump and the REZ adapter kit aren't pictured. I still need to purchase p/s hoses, brake lines for the fronts, and some new dust covers for the inner tie rod ends.

The plan is to remove the front clip of my truck intact, jack up the frame, suspend the engine, remove the existing front-end (cross member & all) clean & POR-15 everything, then install the new cross-member, the master cylinder, p/s box, p/s pump and all the lines. Then put the "dog house" back on as it was - well, that is except for new isolators under the core support.

whew! you guys really know how to bury a post!

Re: '89 3/4T 'burb front-end swap to '66 C20
 

You have done a nice job of cleaning up the front crossmember. Amazing how a garage accumulates stuff, isn't it! Looking good!!!

Re: '89 3/4T 'burb front-end swap to '66 C20
 

........post the pics first:D. J/K....looks like good progress and you will be very happy with the results, I'm sure. I'd like to see a pic of the truck when it's in 'traction' with that whole R&R going on:lol:.

Re: '89 3/4T 'burb front-end swap to '66 C20
 

Sounds like a good plan. I am anxious to see the finished project. I'm sure ya are aware thet POR-15 is some nasty stuff if not properly ventilated. It does the trick though!

Re: '89 3/4T 'burb front-end swap to '66 C20
 

It's amazing how a minor thing like a near fatal event can change your priorities, and stall your progress. I've got back and knee problems and it's taken me several weeks to get half done sanding my truck for new paint, but I'm greatful I can still do it at all.

It's good to see you're again capable of moving forward. What you've done so far looks great.

For what it's worth, I also did the front suspension swap with the engine in the truck. To suspend the engine, I bolted a couple of chunks of frame rail from the donor truck, to the 1955 engine mount holes at the front of the block, and rested the other end on top of my frame. It was simple and didn't require an engine hoist to be in the way.

Also, on the POR-15, you may want to check out the following link, and the testing link within that thread that shows a salt water test comparison: http://autobodystore.com/forum/showt...ht=por-15+rust

We painted my entire chassis and suspension with POR-15 about 10 years ago, and I must admit I'm disppointed with how it's held up. When I wash the crud off there are quite a few rust pits popping through. I found out about Zero Rust after I had completed the chassis, but I've been using it on everything since and I think it holds up better. My truck did see 9 years of Idaho winters and gravel roads so maybe nothing would have held up. Just something to consider.

Re: '89 3/4T 'burb front-end swap to '66 C20
 

Thanks for the tips I was thinking of doing something like that to support the engine. I bought a whole boat load of POR-15 back when I purchased all my parts so I'm committed now. besides, the back sides of all my body panels are already coated.

Re: '89 3/4T 'burb front-end swap to '66 C20
 

that is one sexy cross-member :thumbs:

Re: '89 3/4T 'burb front-end swap to '66 C20
 

I agree, that stuff is deadly if you were to inhale the spray. I take the usual precautions I wear a mask, and rubber gloves and make sure the area is well ventilated, but I also brush it on.
I do this for many reasons:

1. Atomized POR-15 would be deadly
2. I don't think I could ever clean it out of my gun
3. I would have to thin it with Trimethylbenzene a.k.a. Naphtha which is in itself very bad stuff.
4. Thinning it has to affect the durability of the application.
5. The "self leveling" properties of POR-15 is incredible. I have never seen a brush stroke on a finished project.

This kinda makes me nervous can I ask you a couple of questions?
Did you prep all the surfaces with POR-15's "Metal Ready" before applying the paint? Did you spray it on or did you brush it on?

Re: '89 3/4T 'burb front-end swap to '66 C20
 

Good deal, I didn't mean to say you weren't competent, I just have heard some really bad stull, like livers shutting down ect. from lack of proper use. I know it works wonders in the area of preservation.

Re: '89 3/4T 'burb front-end swap to '66 C20
 

No, I didn't find out about Metal Ready until years after I finished my chassis. Like you I brush painted mine after wire brushing everything to bare metal. I also didn't want to render it aerosol due to health risks. It might have held up better had I used Metal Ready first.

I wish more hobbyists considered the safety aspects of the current paint products. POR is no more deadly than anything else with isocynates in it, but that's the component that can kill you. I've known lots of guys that have sprayed catalyzed paint with nothing more than a respirator (including myself when I was younger), but the iso's can be absorbed through your skin and eyeballs so you really need breathing gear for spraying. That's why I painted my truck in lacquer years ago. About 6 months after I was done the breathing gear dropped in price from $2000 to about $500, and I was disappointed I hadn't waited so I could have used better paint. Even if using old Alkyd enamel which is reasonably safe, if hardener is added that has isocynates in it. This is the main reason I'm painting my truck Blitz Black (air dryed enamel). I'm too old to give up any more lung capacity and this is my last paint job so I don't want to invest in breathing equipment that will only get used once.

Re: '89 3/4T 'burb front-end swap to '66 C20
 

Well, the day has come for the deed to be done. I've been forced to take a week off from work (company wide shut downs) so I'm taking advantage of the opportunity to work on my truck.

Day one - tear down:

This goes bye-bye and gets replaced with REAL power steering!!!!

Re: '89 3/4T 'burb front-end swap to '66 C20
 

Wouldn't it be nice if they went back together as easy as they came apart?!

Not sure how well the power linkage system worked, but having the integral power box changed mine from miserable to nimble.

Re: '89 3/4T 'burb front-end swap to '66 C20
 

That's what I'm counting on!! I don't know what the "power assisted" steering felt like either - it's been disconnected since I bought it 15 years ago. I hooked it up once when I repaired the p/s engine bracket, but all the hoses leaked like a red fountain. At the time, it was too hard to find hoses for so I just never got it going again.

Re: '89 3/4T 'burb front-end swap to '66 C20
 

Right on!
Nice progress!!!

Re: '89 3/4T 'burb front-end swap to '66 C20
 

Day two: Partial frame-off

My buddy John came by today and we kicked some tail!

http://pic90.picturetrail.com/VOL225.../374106027.jpg
This is what we started with at about 11:00 this morning (John needed his beauty rest) While I was waiting for him, I hooked up the battery and just drove it in under it's own power (easier on the back)


http://pic90.picturetrail.com/VOL225.../374106042.jpg
Jacked 'er up, yanked the tires. those drums are almost new - shame!


http://pic90.picturetrail.com/VOL225.../374106063.jpg
Dropped the sway bar & the steering box.


http://pic90.picturetrail.com/VOL225.../374106051.jpg
Plucked the brake booster & master cyl.


http://pic90.picturetrail.com/VOL225.../374106055.jpg
Then we popped the motor mounts free, attached a chain to the front of the motor.


http://pic90.picturetrail.com/VOL225.../374106058.jpg
Then we shoved a 2x4 under the front pulley to support the engine - worked like a charm!


http://pic90.picturetrail.com/VOL225.../374106070.jpg
We dropped the old cross-member out and the frame was bare finally! Really dirty, but free of parts.

Re: '89 3/4T 'burb front-end swap to '66 C20
 

Day Two Continued:

http://pic90.picturetrail.com/VOL225.../374106073.jpg
Removing the dirt was easy - I just transferred all of it to my body! My wife tells me I'm a dirt magnet & I guess this is proof!


http://pic90.picturetrail.com/VOL225.../374106081.jpg
Shazam! The dirt just flew off! I sprayed degreaser on the frame, scrubbed it down with a scrubby, then I washed it all down with the garden hose. Then a thorough wash-down with brake cleaner then I let it dry. Now that's a clean frame!


http://pic90.picturetrail.com/VOL225.../374106086.jpg
Next came the Metal Ready treatment from POR-15. I sprayed it on liberally from a spray bottle and let is stand for about 20 minutes. Then I hosed it all off again and blew it dry. The white residue is zinc phosphate an excellent rust inhibitor and etching compound for the paint. This is what you want your metal to look like before you apply POR-15


http://pic90.picturetrail.com/VOL225.../374106093.jpg
I used a propane torch to heat up areas where water would be trapped. All water needs to be removed before the paint goes on.


http://pic90.picturetrail.com/VOL225.../374106097.jpg
because of it's self leveling characteristics, you need to apply thin coats. This is how much coverage I got out of a single dip of the brush. I pour the paint into a little custard dish so I won't contaminate the can.


http://pic90.picturetrail.com/VOL225.../374106099.jpg
There! Done for the day! The finish is so smooth it looks like it was powder coated. After I was done, I wet the shop floor down to speed up the curing time. POR-15 cures by pulling moisture out of the air, so the more humid conditions are, the quicker the drying time.

Re: '89 3/4T 'burb front-end swap to '66 C20
 

looks great so far, I will be doing a swap like this in the future, so I am curious to see how this turns out.

Re: '89 3/4T 'burb front-end swap to '66 C20
 

Very nice pics and commentary!!!

Re: '89 3/4T 'burb front-end swap to '66 C20
 

We should have most of it done tomorrow. And I didn't need my beauty sleep. Trying to get a 7 y/o ready for school is hard enough. I hope to have him out of the houst by 8 tomorrow so I can get up there at 9. Make sure you eat breakfast because I am not going out for any. We need to Git er Done. :sexy:

Re: '89 3/4T 'burb front-end swap to '66 C20
 

begining of day 3:

I've had me oats laddie & I'm waitin' on yoo!



Oh & just so you know, you do need your beauty sleep.

Re: '89 3/4T 'burb front-end swap to '66 C20
 

Looks like 9:30 for me. Arival time that is not departure. ;)

Re: '89 3/4T 'burb front-end swap to '66 C20
 

Day three - Re-construction: "Let the Games Begin!"

John & I started the day off making a list of what we wanted to accomplish today, and then another list of what we needed to buy to make that happen.

Today's objective was to get the crossmember installed, engine bolted in, steering box & brake booster installed. We tooled down to the hardware store & dropped a cool benjamin on some new shiny zinc coated grade 8 bolts, nuts, washers and some shop supplies.

Then we headed back to the shop to dig in.....

http://pic90.picturetrail.com/VOL225.../374175101.jpg
The "new" cross member goes up for the first dry fit!


http://pic90.picturetrail.com/VOL225.../374175106.jpg
The six 1/2" bolts on the bottom fit perfectly and so did 2 of the 4 on top. All together 4 out of 14 had to be drilled.


http://pic90.picturetrail.com/VOL225.../374175111.jpg
This bolt on each side needed to be "augered" out a bit...


http://pic90.picturetrail.com/VOL225.../374175114.jpg
And this one needed a new hole to be drilled.


http://pic90.picturetrail.com/VOL225.../374175118.jpg
New hole drilled....


http://pic90.picturetrail.com/VOL225.../374175119.jpg
This one elongated just a smidge.

Re: '89 3/4T 'burb front-end swap to '66 C20
 

http://pic90.picturetrail.com/VOL225.../374175122.jpg
For the record: the '60-66 engine mount perches will work with the later model crossmembers without drilling any holes!!!


http://pic90.picturetrail.com/VOL225.../374175125.jpg
Rebuilt '89 power steering box installed with Rez kit. (not as much fun as I thought it would be)


http://pic90.picturetrail.com/VOL225.../374175129.jpg
New power brake booster, dual reservoir & proportioning valve installed coutesy ChevyDuty 2005. I sure hope they put some more work into their "adapter" bracket. - we needed to drill 4 new holes to make it work - none of the factory holes line up.


http://pic90.picturetrail.com/VOL225.../374175133.jpg
Mission accomplished!!! Nice day's work!


http://pic90.picturetrail.com/VOL225.../374175139.jpg
Here you go dad, here's your reward!

You boys are fast!!! I started in July and I'm about the same place as you are after 3 days!! ( I keep getting pulled off task by wife and kids)
