Crossbreed
 

Picked this up around March 2016. I've made a few posts in the "what did you do to you blazer today" thread and decided to start a build thread to share all the progress.

Let's start with the purchase. I found it on Craigslist within an hour drive from me. Guy was moving and getting rid of some of his projects. This was listed as a package deal. Two 4x4 blazers and a 2wd C10 long bed for $6500. I wish i could have taken them all but I don't have the space for two extra junkers (they were both really rough). Ended up walking away with this 72 blazer for $5500 which was fair but damn I wish I the space for all three.

I've wanted a convertible 4x4 for a while and when I found this in my price range I jumped on it.

A year worth of progress will follow shortly. Looking back through my photos I didn't do a great job documenting up to this point but there's still lots more to come. Below is how it looked right after I bought it.

7" lift (4" suspension 3" body), worn out Mickey Thompson 36x14.50s on 16.5" rims, supposed fresh rebuilt 350 with 400HP (yeah right) and 3/4 ton axles (14 bolt rear and 8 lug 10 bolt up front)

Re: Crossbreed
 

So the intention when I purchased this was to build a cheap truck for a 4x4 challenge between a few of my friends...

When I bought the truck the guy fired it right up but after I had it towed home I tried to get it started several times over the course of three days and just​ couldn't​ make it happen. I guess he knew the trick..

I pulled the carb and rebuilt it. First time rebuilding a carb so I was a bit apprehensive at first but it's really not that complicated so away I went. Got it all cleaned up and put back together. Popped it back on and....... Woohoo success.. fired right up...

At this point I'm thinking hell yeah, I'll be driving this around in no time (hah).... That thought was quickly remedied just minutes later when I started seeing oil dripping under the truck. It was running down the transmission. Let it run for a bit while I figured out where it was coming from and finally tracked it down. Oil was just pumping out between the intake and block in the valley behind the distributor.

So now I'm pulling the intake... Turns out whoever installed it didn't use enough rtv across the valley and there was a spot where the intake never made contact.

Re: Crossbreed
 

Well hell you pulled the intake... why not pull the whole motor and pretty it up real quick? Ok we'll do that. And in the process found some stripped threads in the intake so replace it and the water pump just because it's cheap and I had it off anyway. Frame off restoration still isn't on my mind... Just want to get it driving.

Re: Crossbreed
 

Next up... transmission and transfer case we're a bit leaky so rebuilt those too... another first for me. They have yet to make it back in.

If you're like me you scrolled to see the photos before reading. If you noticed the bell housing change between pictures 3 and 4 congrats, you spotted my first f*** up. Had the trans all back together after the rebuild and rolled it off my work bench. Landed right on the peak of the bell housing and cracked it. So had to choose on replacing the trans or cut off the bell housing and install one of the bolt on bell housings... Obviously I chose the latter.

Re: Crossbreed
 

Well that's all the drivetrain work... We'll talk about rust next.... Still not planning a frame off resto. (Spoiler frame is off)

Re: Crossbreed
 

I didn't even know they sold a bellhousing like that ! How was the old one machined off? How is the new one mounted?
Goof-off by the gallon ? HAHA, all I've ever seen here in Canada is those tiny little metal cans. Something else we can't get north of the border.

Re: Crossbreed
 

The old bell housing was cut off with a sawzall and cleaned up with a grinder. The new one bolts on over top of the pump using the same bolt holes. These bell housings are made for drag racing and what not to act as a scatter shield in case your fly wheel flies apart. These are thick enough to a stop it unlike the paper thin stock bell housing.

Re: Crossbreed
 

So about that rust.... Rocker boxes were practically falling out but the truck did come with a new set. Floor needed the outers patched which became obvious after removing the nice new rockers someone slapped on to cover it up. Here is some of the carnage.

Re: Crossbreed
 

And repairs... Welded the floor patch right below the first bend and after grinding the weld you can barely tell it's a patch.

Re: Crossbreed
 

very nice work, you're right, can't see the seam. the only thing that might cause you problems is the worm drive clamp on the fuel filter, being plastic you might collapse the inlet, they were designed for a spring clamp

Keep up the good work!!!!

Are your tetanus shots up to date?

Re: Crossbreed
 

Thanks, the fuel filter was from the previous owner and wont be sticking around next time the motor goes in. It's actually probably already been tossed out along with the rusty chrome line going into the carb. I'll probably mount a new filter on the hard line along the frame somewhere when the time comes. I don't like hose clamps anywhere really. Speaking of.. I learned this trick a while back, all you need is some cres tie wire and a pop rivet gun.

Re: Crossbreed
 

Little more rust repairs.... Driver's side floor wasn't as seamless as the passengers side since the rust already made its way past the rocker. The quarter had a weird patch of Swiss cheese in it... Though that was an odd place for it to rust out, rest of it was pretty solid.... Anywhere you see the green self etch rattle can primer is where I've already stripped it to bare metal and just spayed that on there temporarily while I work on it. It'll all get stripped again eventually and hit with a coat of epoxy primer. The etch primer actually sticks pretty good but I've grown not to trust any coating that comes out of a rattle can.

Re: Crossbreed
 

Repairs to the forward part of the quarters... Got a little overzealous trying to planish the weld on the driver's side and created little high spots all over (still learning). I've got one of those shrinking discs but haven't​ had a chance to get back to that spot. I'll revisit it again down the road and report back how it turned out.

Re: Crossbreed
 

Oh yeah, had to patch these areas on both sides before doing the fwd quarter patches shown above. Not sure why these are showing up rotated they are oriented correctly on my phone.

Re: Crossbreed
 

Another little patch on the firewall.

Re: Crossbreed
 

Was proud of this patch... Not because it looks exceptionally good but the fact that it was made using just a vise, block of wood and a hammer and dolly.

Re: Crossbreed
 

Looks like I didn't snap a shot of the before and after on this patch but this quarter panel patch was a bit frustrating. Ended up buying 3 different types of patch panel before I got one thatwas passable. Apparently they don't bother stamping that extra detail around the edge of the fender on most of them.

Re: Crossbreed
 

Oooh something exiting going down...... Nope more patches....

Re: Crossbreed
 

First image is a patch the PO put in the floor of the bed... So close to doing a decent job compared to the other hacked up messes that were left behind. Cranked the welder up a little bit higher and went around and filled all the holes he left and gave it a bit better penetration.

Re: Crossbreed
 

Doors getting some attention... Both doors needed the fwd and aft corners patched inside and out.

Re: Crossbreed
 

I'll end on a high note..... Or not... Wish I could say I forgot that this happened. See the extension cords right behind the tool box? Was rolling it and as soon as a wheel caught one of those she toppled right over. About that time a solicitor came up to my garage door and started yapping as I was trying to upright the tool box, needless to say he didn't get my friendlier side.

Re: Crossbreed
 

:metal:

Re: Crossbreed
 

Nice work on the blazer, you're doing some good work. I need to start a build thread, but I work so slow it would drag on for years, and I hate to rush!

As far as the tool box, things like that happen. I was using the grinder with a cutoff wheel and set it down on my drop light cord before it stopped... threw a few sparks and kicked the breaker.

Keep it up, Rg

Re: Crossbreed
 

Strong work. I'm on board.

Re: Crossbreed
 

Re tool box. Man, I thought that stuff only happened to me.

Re: Crossbreed
 

Almost caught up with the present.. body did finally come off the frame. Built a wood jig to tip it on its side.

Underside was blasted, epoxy primed and coated with raptor liner. Still need to put the rocker boxes back on, probably get to that this weekend.

Inside floor has also been blasted and primed with epoxy.

Re: Crossbreed
 

Frame also got some love. Was tough dragging it from the driveway out back onto the deck but managed to get it up there on my own. Didn't want to get liner overspray on the neighbors vehicles.

Blasted, epoxy primer and raptor liner just like the body but I shot the raptor with an hvlp gun instead of the shutz gun supplied with the kit. Really like the way the texture turned out.

Re: Crossbreed
 

Currently working on converting the 14 bolt over to disc brakes. Grinded down the OD of the stock hubs to allow rotors to slide on rather than be staked to the back like most conversion kits. Did this so I could use stock rear brakes from a late model gm. Had to use rotors from a dually to get the backing plate to set far enough inboard to land on the axle tube.

I need to have some flanges made so I can weld them on and get everything bolted up. Anyone know a friendly machinist willing to do such a small job without charging a fortune? Tried several of those eBay machine shops that say no job is too small and can't even get a response for a so I assume it's not worth their time. I could probably get by with just a 1/2" plate plasma cut and not have the raised part.

Re: Crossbreed
 

Almost forgot about these pieces... Bent up using a vise, hammer, dolly and whatever was laying around I could pound on.

Re: Crossbreed
 

I didn't get before pictures of the hack job from whoever put on the 4" lift before I got it. It had 4" lift springs up front and 4" blocks out back.

The spring perches on the 14 bolt were space out about an inch too far on both sides. Whoever installed it just forced the springs out to match and you could see the shackles were in a bind. The axle had some aftermarket shock mounts but they were in the wrong spot as well. I cut off the sping perches and beat the shock mount off with a hammer. The had practically no penetration and some nasty looking welds. I assume they tried to weld over paint/dirt and whatever else was on the axle.

Re: Crossbreed
 

very nice job so far!

Re: Crossbreed
 

Installed the rocker boxes today. Raptor liner sprayed inside and out, hopefully that will keep em from ever rusting out again.

Re: Crossbreed
 

It's frightening what people are driving on public roads. There's tons of stuff like that out there, where some backyard guy goes to Harbour Freight and buys a Chinese 120v flux core MIG welder and now thinks he's a professional welder. I've seen some homebuilt trailers with bubble gum welds that you'd wonder how he ever made it out of his driveway.

Re: Crossbreed
 

Had someone make me a set of flanges for the 14 bolt to mount the newer model disc brakes.

Re: Crossbreed
 

Starting to put stuff back together.

Re: Crossbreed
 

Impressive. Looking forward to more.

Re: Crossbreed
 

I'm hooked ... I need to do the same thing... I like the way you write ... I totally scrolled down and looked at that bell housing photo ... lol

Re: Crossbreed
 

Thanks for the compliments.

I set out to paint and rebuild the drive/axle shafts. Got everything apart blasted and primed. Just orders all new u joints to put them back together.

I got the u joint out of one of the front axle shafts using a hammer and socket... Set out to do the other side and couldn't get it to budge. Starting hitting harder and harder and I finally missed and caught my finger. After that I bought one of those tiger tools u joint presses. Should have bought it before I started.

Re: Crossbreed
 

Making a little more progress. Took the front axle apart and stripped and painted it. Same for the springs and shackles and I replaced the bushings with some red poly ones from
prothane. I also started mocking up the rear axle. Almost have a rolling chassis again.

Re: Crossbreed
 

Finished putting the front axle back together. Had a rolling chassis for one day before getting impatient and putting the tub back on. Probably have quite a few things left to do that would be easier with the body off but the ole lady and neighbors will be happy its not all torn apart in the driveway anymore.
