73 Duster front seat belts for bucket seats

Well I'm wondering what to do for belts as well for my 68 GTS. I'd like a 3 point, but may have to settle for a 2 point. My restorer did 3 points from CI in a 69 Roadrunner and the retractor got in the way of moving the seat back moving. I owned a 69 Swinger in the day, and the upper belt stored over the door. It worked okay, but most of the time I just let the belt hang down.
