85 body on a 74 frame
A friend of mine found a nice 85 c10 for sale that isnt running for a good deal and i want to get it...my 74 is getting quite rusty so my plan is to swap the 85 body on the 74 frame. My question is would this body swap bolt on straight up? My 74 also has a 5.3/4L60e swap so i figured it would easier to just swap bodies

Re: 85 body on a 74 frame
Yes but u will need body bushings for the 85 cab an front end.....also will have to cut the front frame horns at a angle to get the 85 bumper to fit

Re: 85 body on a 74 frame
Its a fairly direct swap, I just did one myself (86 body on 78 frame). You do NOT need to cut your frame horns, but the bumper brackets will need to be modified, which is easy.

Re: 85 body on a 74 frame
that's why ur brackets had to be modified cause you didn't cut ur front frame horns at an angle....if you cut ur frame horns you can use the 81-87 bumper brackets

Re: 85 body on a 74 frame
That sucks. Since you need another motor now, think it would be easier to swap all your ls stuff straight over to the 83 n use its frame?

Re: 85 body on a 74 frame
Yeah actually my buddy who helped me build the 74 said we should just do that instead...btw what gear ratio does an 83 have? My 74 has 3.08s at the moment but would like 3.73s or something

Re: 85 body on a 74 frame
Yes. Always use the frame bushing kit regardless of cab. Ivorton the only best way to find out is pull the cover and count. Plus you can inspect what you're working with.

Re: 85 body on a 74 frame
Get the 1985 vehicle information PDF from the GM Heritage center. You can look up the standard axle ratios based on series (10, 20, 30), 2wd or 4wd, Engine, and transmission.
