1988 Crew Cab shortbed overhaul

Hey guys, Im new to the board but lurked on here for years. I have wanted a crew cab for years and just never found the right truck to restore. I pulled the trigger a few weeks ago and bout this truck. Its a 1988 7.4L, turbo 400 truck with dana 60's. The structure of the truck is very solid and all the cab and bed mounts a re in really good shape. One rocker has some rust and it needs a little mechanical work but runs out ok. I think the truck was restored once before and someone put a later front clip on it. I gave $6200(hope that was a decent deal). I drove it back 4 hrs from middle ohio.

The plan is to short bed, 4l80e, and do a frame off in some fashion. I don't know the in's and out's of the square bodies so feel free to correct me if I post dumb info, its just because I don't know the difference. I have already asked carboncrew a ton of questions and I really appreciate his helpfulness.

Re: 1988 Crew Cab shortbed overhaul

I did add some 35's and wheels I had on my quigley just to give it a different look for short term. These are not permanent. The bed, front fenders, and front bumper are all for sale also.

I drove a couple hours away on thursday and bought a clean short bed, four power doors with clean panels and a wiring harness from a suburban since mine has aftermarket power windows. I also picked up a late model column and instrument cluster.

Re: 1988 Crew Cab shortbed overhaul

Looks like a real nice truck to start out with. Good call on selling off that front bumper.

Re: 1988 Crew Cab shortbed overhaul

We pulled the bed, bumpers, front fenders, and all 4 doors today. Someone glued the carpet padding down so thats taking some time.

Re: 1988 Crew Cab shortbed overhaul

The rear springs already had an Off-road Design shackle flip kit. The truck sits a little to high for me, I may contact deavers for springs. I'm trying to have frame at sand blasting by end of week

Re: 1988 Crew Cab shortbed overhaul

Sweet truck and seems like a fair deal to me. Probably has a 14 bolt rear. I'll be watching.

Re: 1988 Crew Cab shortbed overhaul

Not trying to be a smart ass but whatever someone will give you for it. TBI peanut port head isn't really a motor people seek out for swaps. Your market is probably someone replacing a like-kind motor. Around here I would guess $800-1200.

is this type of cut stronger when completed? i know some that have 'step cut' the frame but also heard that a horizontal weld on a frame isnt desirable. just curious, cool build. i have a lowered ccsb but mine was already cut down when i got it. good luck with the project!

I'm interested in that 454, my dad and I are in Richmond quite a bit. I'm not looking for a high dollar motor though.

For a minute I thought you took a picture from my build. My frame had the same mark in the same white crayon a couple months ago. I did a ton of reading on different forums and articles about the best cut and from what I gathered the 45 is the way to go.

Haha, I did read your build thread and we agreed at my shop that the 45 was the way to go also. Once you weld and fish plate it on the inside , its solid and Im comfortable with the fab work.

Just for guys looking to cut the frame, it is exactly 14" in the front. The front two bed holes need to 10 3/8" apart. The holes were originally 24 3/8" apart.

Id sell it complete for $800. i just listed it locally yesterday and should have it out today. I own a transmission shop and Im using the TH400 for an off road desert truck build for a local customer.

Re: 1988 Crew Cab shortbed overhaul

100 sf will get all the floor, most of the roof and a good bit inside each door.

Re: 1988 Crew Cab shortbed overhaul

We got it down to the frame now. I'm gonna keep the axles under it till he can sandblast it next week. I'm surprised how at how clean the frame was around the body mounts.
