Well that explains it, I bought a Mopar parts group with 95% of the group being 2nd gen Charger stuff. So I'm guessing at what parts are from either 68, 69 or 70. So not knowing their origin I've always wondered about the 6R & 6L on those belt clip brackets. I never got around to asking on here for the experts to help out.

Thanks

Are you still buying seat belt bolts?
