Flywheel questions...

Yep I assumed, and that pretty much sums it up on my part. I would also assume that an 11" 26 spline 1 1/8" GM clutch should be a workable option. I have mixed and matched a couple times before Mopar flywheels and GM clutch applications and the bolt patterns interchange fine. I believe pretty much any GM/Borg Warner/Passenger car used the clutch you need.
