Nice build and great work on it! Nice work on those cab mounts. I have a 72 gmc cab that is on a 03 half ton burb chassis and the guy put the front cab mount bolt straight through the frame. It works, but IDK if I'll complete the project or separate it.

Re: C20 to K20 Conversion "Simply Toxic"
 

Thanks Dieselwrencher, I did a good bit or research on how the cabs fit the frames before hand. Came up with something that looked better then some of the ones I saw. If I was to this frame swap again I think I would have picked a burb or a avalanche frame to start with.

Worked out in the garage almost all day Saturday tearing the cab apart. Found a bit more rust, so I need to order a few more pieces before I can start going back together. I want to thank 72_tigger for helping with the cab last weekend. Not going to explain all the rust, I'll let the pictures do the talking.

A few more pictures of the rust.

Re: C20 to K20 Conversion "Simply Toxic"
 

Nice job on the cab mounts and I really like your rotisserie the cab is on. That will really help in repairing the rust on the cab. Nice job!

Re: C20 to K20 Conversion "Simply Toxic"
 

Thanks landarts, glad I took someones offer on letting me use the rotisserie, its made life way easier.

Re: C20 to K20 Conversion "Simply Toxic"
 

Figured after two days of working on the cab I'd have more done. I got the new driver side floor welded in and the cab corner started. Still have to do everything to the passenger side.

Re: C20 to K20 Conversion "Simply Toxic"
 

Making good progress- always surprising how much thin metal you find when you dig into it

Re: C20 to K20 Conversion "Simply Toxic"
 

Yeah, the more I vibrate the cab taking the driver side apart, the more I see I need to replace on the passenger side. Just ordered a floor board for the passenger side, it looks like Swiss cheese since I took the rocker off.

Re: C20 to K20 Conversion "Simply Toxic"
 

Forgot to post the floor pan pictures the other day. Got the rocker and cab corner lined up last night. Need to take the outer rocker back off to finish the inner rocker. Give everything a final grind, then time to move on to the passenger side.

Re: C20 to K20 Conversion "Simply Toxic"
 

Floor patch looks great, keep up the good work on bringing it back to life.

Re: C20 to K20 Conversion "Simply Toxic"
 

Nice work- do you think you should take the cab off the rotisserie and mount the doors before you weld the outers on? Just to make sure everything lines up? Just my .02

Re: C20 to K20 Conversion "Simply Toxic"
 

Normally I would say yes to taking the cab off and fitting the doors first. But in my case the bottom of the doors are rusted out and I have all the metal to fix them, so I'm just going fit the doors to the cab. Kind of a backwards way of doing it.

Re: C20 to K20 Conversion "Simply Toxic"
 

Thanks

Re: C20 to K20 Conversion "Simply Toxic"
 

Finished up the Driver side last night, now just have to seam seal and grind everything smooth. Should see the new passenger side floor board before the weekend, hopefully be able to get that started and finished in the next week.

Re: C20 to K20 Conversion "Simply Toxic"
 

Looks great!
Can I mail you my truck? :)
Mine's slightly better to start, but even southern ones rotted.

Re: C20 to K20 Conversion "Simply Toxic"
 

Thanks, I don't think there are too many of them that don't have rust on them.

Re: C20 to K20 Conversion "Simply Toxic"
 

No pictures to post today, but after having to wait to get a second passenger side floor board shipped to me, I got the passenger side installed last night. Got both in from Fedex damaged so I ended up using the one with the least amount of damage.

Re: C20 to K20 Conversion "Simply Toxic"
 

I got the passenger side floor board welded in and the passenger side rear cab cut completely out this weekend. Was only able to work on the truck here and there as the wife wanted to go to IKEA and furniture store. But first couple pictures are of the completed driver side I forgot to post. Then some in process of the passenger floor.

Re: C20 to K20 Conversion "Simply Toxic"
 

Shows how much I had to cut out of the passenger side cab corner. I have to remove the plates that are in the back of the cab too and weld in some new metal under them. I followed a bunch of rust the more I cut into it. Since the new rear cab support isn't exactly the same as the original, I decided to put the cab corner on first and make sure that is all lined up before I messed with the floor and brace.

Re: C20 to K20 Conversion "Simply Toxic"
 

Almost forgot to post this. Decided to scrap the Dana 44 front axle, went and bought a Dana 60 king pin axle. Came out of a '79 Ford F-350.

Re: C20 to K20 Conversion "Simply Toxic"
 

So this passenger side has been fighting me the entire way. The lower A-pillar and B-pillar are completely different then stock. To the point I had to cut the B-pillar apart and add metal to it, and on the A-pillar I'm going to have to modify the outer rocker. Once I figured that part out I ended up building a piece for the rear of the cab and modifying the inner rocker piece. Still need to grind the welds and do a bit of metal finishing and it'll be all good. Have I said how much I like this re-stamped metal yet?

You’re burnin’ up some wire! Going to be a solid cab when you’re done

Re: C20 to K20 Conversion "Simply Toxic"
 

Looking good, a little grinding and paint and she will be like new again. Nice job saving this one!
