I have looked threw 18 pages of posts for nv4500 swaps. I have a 1986 Chevy k30 crew cab. It is a original 454 th400 truck. Someone had swapped a Sm465/ np205 with a mechanical clutch setup. The clutch went south on it & 2nd gear was jumping out on decel. I am in the process of swapping in a 1999 nv4500 and np208 into the truck. I have the hydro throw out bearing hooked to a original type master cylinder. My stupid question is which clutch and flywheel do I use for this setup? Thanks for any help.
