Featured here is a lot of NINE NOS GM rear end/differential gaskets for your 1963 - 1979 Corvette.
GM # 10132893
You are purchasing 9 NOS GM gaskets in the GM packet.
I opened the packet in the late 1980's to remove one gasket when I rebuilt the rear end on my 1965 Corvette.
Gaskets are in excellent, NOS condition.
