78 C10 questions

[Gnarlyrider27]

Okay so I have a 78 Chevy C10 heavy half. It was my first car I ever bought and been a work in progress. Well I just found on facebook a guy selling a 88 Chevy 1500 4x4. Missing body parts but everything else is there. I want to put my 78 cab and everything else body wish on that frame. Do I have to do a lot of mods and cutting on the frame and mounts or should the cab bolt up and stuff. Buying the running truck for 250 bucks which is cheaper then buying all the stuff to convert it plus I want the newer engine.
