Default New clutch

So I bought a used Fidaza.
New Ram pressure plate from Jerry.
New Ram hydraulic throw out from Jerry.
Clutch disc from Jerry.
New PP bolts and FW bolts form Jerry. Fidanza says use the OEM size bolts.
Working on beam plates from Bill B.
Hurst short throw.

Anything else I should do while in there? Other than sending my gear box to Bill B.
I almost missed the beam plates.

Marc H. would caution against using the needle bearing pilot bushing. Too many parts for things to go wrong. Keep it simple w the bronze.

Note that a bronze bushing often comes loose and spins in the crankshaft. Installation of the bushing with bushing retaining compound will not solve the problem. I recommend to use only the roller pilot bearing. It will never come loose. GM PN 14061685.
