Jeff,

Thanks for the offer. Let me get the motor out this weekend I'll get back to you once I find out what else went wrong. I believe I need some other parts; do you have the new bolts for the cams or only Marc? Anyway I'll make the list since the clutch will be last; I just was in between the other stuff and wanted to figure out what issues with the clutch as I pulled it.

Aloha!!

I found the L98/LT1/LT4 GM part number 10079898 just in case someone needs it. This is from a post of the ZF Doc via internet search.

Back from the dead.

Hi guys, I'm new to the forum and do not own a ZR1 Vette. However you guys do have the best info on this LT1 pressure plate bolt fiasco.

I am putting an LT1 T56 trans into my '87 IROC. And I finally found a place that seems to have the correct bolts. McLeod part number 1502.

However my problem is my nice new SPEC steel flywheel does not have the counterbores in it. So does anyone know the diameter of the counterbores in the stock flywheel? Is it just 3/8"? I am going to take the flywheel to a machine shop to have the counterbores drilled.

Thanks,

John

Please refer to post #4 above foor the bolt dia. Counterbore size would be as close to 0.376" as you can reasonably get. The tighter the "slip" fit, the better.
