Hi everyone! I'm restoring a -68 Skylark coupe, and going for 3 point retractable belts in the front, does anyone know if you can assemble 3 point retractable seatbelts in the back seat? Has anyone done that? I'd like the whole family to travel safe... What do you guys think of the company RetroBelts? Thanx in advance for input, I'd love to see some pics of this if anyone have! /Anki
