1990 zr1
Did the ZR1 use the same ZF6 speed as the base car? If so did the ZR1 have a dual mass clutch or did it have a standard flywheel. I remember reading somewhere that the gear box was the same manual on all 1990 cars, but that the ZR1 used a single mass (standard) flywheel and used a longer throw out fork?=left

Thanks for the input.

The ZR1 stuff is different.
The ZF 6 speed has a different length on the input shaft than the L98/LT1/LT4.
The LT5 uses a dual mass flywheel but it does not interchange either. It has a different number of bolt holes that attach it to the crankshaft.
I am not a ZR1 expert, so you might get more info from others too.
Also take a look a ZFdoc's web site. It lists some of the info for the ZF transmissions including part numbers, dimensions, etc.
Good luck.
