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.
