Frame swap questions

Im sure this has been asked before but Im hoping someone knows right off the top of their head. And I realize some of you might think this is a bad idea but that isnt the question.

A friend just called me and asked this. He wants to know if you can take body off of a 68 K Burb and put it on a 72 C coil spring truck chassis. Wondering what all he has to change.

Then he wants to know if he can put a 71 truck cab and box on the 68 K Burb chassis. Ending up with a 4x4 truck. Again what all needs to be changed.

I think hes hoping maybe only the rear frame horns and body mount points need to be changed for both of these swaps to work.

Thanks for any insights!

Re: Frame swap questions

Park Brake System (handle vs foot) Throttle linkages (cable vs rod) Rear light harness is routed different for the truck vs burb, Fuel tank and lines, If I am right there is a difference in the rear mounting tabs for the C and K Burbs. My buddy has a K and I can ask him because we went through that and he came and checked a C frame I had. We have both frames and it wont be hard to compare them.

Re: Frame swap questions

I know that the Suburban rear frame horns are different than the pickup ones to put the sport bumper in the proper location for a Suburban. Mounting of a standard step bumper requires modification of the Suburban frame.

I also remember reading here some time back that the shape of the frame rails under the box of a pickup are quite different than a Suburban.

Good Stuff!! I have a coil spring 2wd truck frame and my friend has a 4wd burb frame, we can check the rear frame rails to see if there are issues with the bed mounting as stated above if you want me to.

Re: Frame swap questions

Ill ask my buddy first, I appreciate the effort but you dont need to do anymore leg work (yet lol). Someone he has been dealing with for awhile offered him a trade for a later model (90s I think) 3/4 ton truck he's been sitting on. Stuff he wants to trade is the 68 burb 4x4 a 71 truck cab and a bunch of other 67-72 truck stuff. Sounds like the Burb has some rust issues so he's not going to make a decision until he sees it in person and that wont be until after the holidays.
