I've got an 01 RCSB Silverado 4.3/5spd. I've searched a lot on this swap, and I think I have most of it covered, but I'm still not sure what all my flywheel options are.

1. If I'm just swapping the LSx in and keeping the NV3500, I know I just need the flywheel/clutch for an 01 4.8L, and can use my slave. (same part#)
But 99-00 has all different part numbers than 01-up. Is it possible to use 99-00 4.8 flywheel/clutch/slave?

2. If I'm swapping to LSx & T56, can I use the 4.8L flywheel/clutch/slave, or do I need the F-Body flywheel/clutch/slave/starter?

3. On car-part.com The F-body flywheel cross referenced to the Vette flywheel. Is this accurate? I've found discrepancies on there before.

Any info is appreciated. Thanks, Chano
