What bolts for the pressure plate? Help is much appreciated don't want to have to pull it out again later thanks

    Good evening Homer. New to this thread and working through lots of info. It looks like you completed exactly what my son and I are attempting. A 1994 GMC 1500 4x4 - had 4.3 V6 originally. Putting in a 2006 6.0L and bolting up to original NV3500 5spd.

    Wondering how your project turned out?

    I had test fit the engine to the tranny using a 4.8L flywheel (LUK LFW387) and the throw out bearing did not contact the clutch. I am hoping the fly wheel is the issue.

    Iím about to swap a 99 5.3 into my 2001 rcsb 2wd truck. Originally a 4.3 5 speed.
    What exactly do I need to mate the 5.3 to the nv3500?
    Is it just a 4.8 flywheel? My truck just got a new clutch kit installed but the engine decided to torch the head gaskets haha. Hoping I donít need a whole new clutch assembly......
