Manifold Adapter Kit, O-Ring to Band for Harley-Davidson

The pre-1978 manifold is sealed with O-rings between the cylinder head and the manifold.

Includes adapter rings that will work with: O-ring heads and O-ring manifold, O-ring heads and band style manifold, and band style heads and O-ring manifold.
The kit includes four adapter rings and two stroke adapters to convert the stock manifold to cylinders longer than the stock length.
