Alright K5blazin, I got this figured out and it works. The LS2 pilot bearing is the key, it is larger and goes in the very end of the crank instead of recessed back in like others. I did purchase the LS2 flywheel bolts they are the correct length and I believe are TTY or torque-to-yield so you don't want to just throw anything in there. It might be tempting to use the flexplate bolts but don't do it.

So all in:

flywheel (99-06 4.8L/6.0L manual trans) $60
12" clutch kit $120 (or whatever fits your SM465 - 11"?
pressure plate bolt kit $12
LS2 pilot bearing $18 (critical!)
LS2 flywheel bolts $40

$250 all new parts, not too shabby! I'll be doing a write-up with picture including aligning the bellhousing, since it is critical for trans life to check the runout and make adjustments.
