93-97 T56 (LT1 style), has the correct bellhousing to mate to the later model 1 piece rear main. I used everything from the LT1 (Clutch, pressure plate, flywheel) and it bolted up to my 86 up block and works great. I used the Tilton 7/8" master cylinder with a stainless braided clutch line to the late model T5 Slave.
EDIT: Nevermind, I see your talking about the earlier style block. Not the same deal, sorry about that.
