Anybody know of any good used seat belts for sale? My 68 is in dire need of front Lap & Shoulder Belts. I have the Rears and the ones that are attached to the Roof, but I'm missing the Retractable ones, both sides, and the ones that the shoulder harness snaps into. The belts are Black and I believe, not sure, the Tag should read "Irving 1968 - Model #231 - 27-A-68". I know some of the Camaro Parts Houses list the new ones, but I'd like to find used if possible. Any and All Ideas would be greatly appreciated.
