Dual Mass Flywheel interchangeability
I've been asked whether a 1989 L98 dual mass flywheel is interchangeable with a ZR-1 flywheel. I do not know the answer, although I can see that the GM part numbers are different - 10174481 for the LT5 and 10174482 for the L98. Can anyone help to broaden my knowledge on this subject please!?

Re: Dual Mass Flywheel interchangeability
L98, LT1 & LT4 flywheels all have 6 bolts to crankshaft, LT5 has 8. As Yun said, not interchangable.
