REPRODUCTION. You are purchasing one carburetor insulator spacer. This is used on Rochester 4GC or Carter AFB carburetor single 4-barrel (4BBL) applications. Replaces Part # 1473021

The grooved side goes towards the carburetor. Starting at the manifold, the stack of parts is as follows. Gasket, insulator, gasket, tin plate coated on top with gasket cement, and finally the carburetor.

PLEASE NOTE: Compare to yours for proper fitment, some vehicles may have been "retrofitted" to use the later style insulator for 1963-1966 models that incorporates a PCV fitting on the insulator spacer. If this is the case, please use our insulator spacer for 1963-1966 carburetors.
