this may end up more like a poll, but here goes I have found a 79 K5 that I want to pick up mostly stock that has a much better body than my 84( Michigan salt cancer) and want to drop my 454 in here. setup is stock axles(10,12) th350/np203 (no twin stick, yet) and the cap is missing pass. glass and some interior panels. what i wanna know is from you more experienced guys what is not going to be interchangeable because most of it is, right? and if I pick it up who needs what from an 84?
