cleaning out some of dads parts collection since 1966. I've got a really nice exhaust manifold here that was removed from a 350 HP, 1970 corvette in the mid 70's. he may still have the mate to it, but I haven't finished my search. grandpa started the shop in 1919, and much has been accumulated since. this has a date code of JAN 1970. no reproduction junk here. 100% authentic GM. dad is also willing to look at offers. thank's
