Copper Exhaust Sealing Ring Bus '75-'78

Copper gasket that seals between the cylinder head and heat exchanger or manifold on '75-'78 Bus with type IV motor. Priced each. 4 required per vehicle. We sometimes substitute the earlier part, 021 256 251A for this part, since the earlier part is slightly wider and can help make a better seal. See link in 'Related Products' for the alternate part.
