The original bolt did not have a shoulder (earlier what I called a lip) under them. Once the rear ends got to the '75 or '76 era, the taller headed bolt with the shoulder started showing up. I moved a '76 Seville 8.5 10 bolt hsg that Id thrown a posi in during a yard run, its original hose asm had the taller headed bolt.
Am building more modular housing racks, they accept 14 rearend housings in minimal space, and am in the process of moving. The housings I have, I personally pulled out of parts cars or are out of my own keeper cars and am very confident in the originality of the fasteners. Feel free and drop me a PM, can get you a pic to a phone #. If you don't care about head markings, can send you one of the previous mentioned correct length bolts off a '69 hsg.
