I have a NOS 1971 Mustang with a 429 CJ or SCJ oil adaptor assembly. This part comes in it's original Ford box and has the number D1ZZ-6881-A on the box. Both gaskets and the bolt with the gasket are included. The one bolt head has some lt surface rust that will need the be cleaned up. They are asking almost $2000 on ebay for one of these. Price on this one is $750 plus shipping. Email gandcmurphy@rogers.com if interested.
