I have 2 rebuilt harmonic balancer's for sale, they fit the 63,64 Olds 394. Both have been revulcanized with the latest high tech polymers. So I would like 150.00 for the 2 groove and 200.00 for the 3 groove. Both come with a transferable lifetime warranty receipt.

All others who aren't registered members, Shipping will be 15.00 in the lower 48, all others request shipping quote. Will consider trading for other parts, what do you have?
