Hi John, Sorry I didn't see your response until now!! Missed it ~ If you still need this info, see these pics. Its just a collar of lightweight steel. If your still in need of it, private email me your address and I'll send it to you. "For the Good of the Brotherhood"! Let me know if you need the bolt.
