One of the guys in LSC is swapping the factory 4 spd in 76 for a 420, he has the Adv bell housing, now with some type centerforce clutch.
I have set him up with a cast iron bellhousing, but does anyone know if the clutch and PPlate in there now will work with the 420?

10.5" stock chevy clutch, plate must match the TO bearing. pretty standard chevy. From what I recall the AA bellhousing wasnt that different.
