Our catalog record for this one is thin, just the one listing spanning 1971 to 1972. It sits under the Cylinder, Cylinder Head and Fittings figure, which is the right neighborhood for this kind of gasket.
Given the sparse record here, best to call the shop or have your engine details handy before you order, so we can confirm it's the right gasket for what you're rebuilding.
