I’m trying to think if what I’d like is even possible. Modern belts retract from the shoulder. This would have to retract and “float” from the lap belt. That may not work. I need to think about this for a second.
If you want it to retract from the shoulder, you've got no where to put the retractor. There's no hidden space up there, it would hang off the hard top structure. Modern cars put all that stuff inside the B pillar, you don't have one. And modern cars have larger pillars anyway.
The ones from seatbeltplanet work just like the originals with the retractor on the mounted to the floor/rocker, with just a shoulder loop that hangs down from the upper anchor.
