Actually I didn't. The car was a 67' and it didn't come with seat belts. I did this ten years ago when I was younger and more foolish. I didn't think anything about driving without seatbelts. Nowadays my daily driver is a Mercedes with ABS brakes, airbags and whether it was required by law or not I would still wear seatbelts.

As far as belts in this scenerio I would think later style belts would be the ticket. So I guess you would have to weld in the mounting spots on the chassis.
