I am new to this site, but have been a chevy dude all my life! Anyway I have a project going on and am in need of some help. I have a 79 chevy 4x4 sitting on 42 swampers and thought that it would be cool to put a 89 Z71 body on my chasis. I have the body off of the 79 already and the bed off of the 89. from what I can tell this ain't going to be a real easy job. Has any of ya'll ever done this type of swap? Would it be better to just change all of the drivetrain to the 89 frame? We have a bog in in 3 weeks and I don't have alot of time to get this done. Any info will help and I thank You in advance!

 

I got the 89 cab on the 79 frame. The front mounts lined right up with some holes that were already there and I don't see any problem with them. My new question is where the 79 mounts are on the frame I am going to have to drill into the body and mount it like that. Is this going to be a problem? the 79 frame is around 8.5 inches narrower than the 89. If I mount this like this will it hold up? anybody?

 

i would try to bend some sheet steel to the shape of the cab and weld it on for extra security, does the frame still rest on the c-channel?

 

No, I am pretty sure that it's just the floor board. This is a mud truck only, so I wasn't really going to worry about it a whole lot, but if somehow it turned over, that might be bad.
