I have a new in box C.A.T. flexplate to fit smallblock chevy with one piece rear main seal.This will fit 5.7-4.8 v8 or 4.3 v6. This is a S.F.I. approved for racing at upo to 12000 rpm.And is MUCH stronger than a regular flywheel. It sells for $89.00 in summit. My loss is your gain. I will NOT answer text messages ! Please call . thanks.
