I have a 94-95 Chevy 4x4 nv4500 and I have a early style 2wd Cummins nv4500 (the shift tower and shifter is like an old 4 speed style). I've heard of input shafts being swapped and making a Chevy trans work on a Cummins. Just wondering if anyone has personal experience or facts on what can be done and what can't? Is it cheaper to go with the adapters? I just have a lot of parts for 2 different projects and thinking of making one
