I've been searching for a used cobra or edelbrock performer 5.0 intake on the classifieds and ebay. I know I need the intake elbow(unless I buy a 94-95 cobra intake). I see that most of the "new intakes" have gaskets and hardware that come with them. If I buy a used intake where could I find these gaskets and hardware? How much more am I gonna pay for the new gaskets and hardware?
