If Bob does not have them, you can find them on Ebay all the time. I know of a set from a 69 LeMans. I don't think they are the same buckle style.
Word of warning: :Smarty: Be VERY cautious about using old belts, if they've ever been stressed in an accident, they should NOT be re-used, and it's hard to know their history from ebay. If you want original-style hardware, you can get new webbing and a GOOD upholstery shop can swap it out, or there are some repros being made/sold, like these at: Andover Restraints: http://www.andoauto.com/seat_belts.htm (Thanks Walt Kilgus for the link!)
