I forgot to mention, the flywheels floating around made by Jerry W were drilled for the 5 cyl clutch pressure plate, not the 4 cyl (different diameter for whatever reason). I can't verify that as I went another route and drilled my flywheel for a 10 1/2" GM pressure plate (LuK 04-109). It also has the 26 spline clutch disc....came off a late 80's Pontiac/Firebird. Requires removing a smidge of material height from the bearing retainer.
