Have some vintage NOS Chevy BB gaskets
 

have a few NOS (and back in the day NOS) BB Chevy engine gaskets pair of P/N 3976081 (supposedly ZL1, various BB.?) pair of P/N 359936 silver cork oil pan gaskets and a ( I think)BB timing chain cover gasket kit that I cannot read the p/n off of. This stuff is from the late 60's, early 70's. Any help IDing would be appreciated. Thanks
