What do I need to know? I’m looking for info on the things that aren’t obvious. Everything on both trucks is factory. I’m considering using the’98 4cyl rear. ‘96 4.3 is a W code.
What I’m thinking about is basically a sheet metal swap. The 96 is a very nice rollover and the 98 can supply the body. I guess I’ll just need to swap all of the wiring from the 96.If you were to move all the interior and wiring from the 96 over to the 98 you would not have the issues listed above... but you would have a hard time later trying to sell a truck that is supposed to have the updated interior. If that isn't a care then strip the cab to empty and move all the wiring over. The lighting in the front will take some mods but not too much. The 96 ABS unit would also need to be moved as the 96 computer wont know how to talk to the 98 unit. It will be a ton of work!
