Anyone found a good 4pt or 5pt seatbelt setup for the bucket seats? I'm looking for one with a click-buckle like a regular car, not a racing link style cam.

Try RJS belts. They have a nice quick release/click style.

All I have to say is if you like your nads go with 4pt. I was in an accident in a car with 5pt(rollover) and I really wished I hadn't been. Of course I've never hit a 4pt to see if it would hold as well but I'm sure someone on here has and can tell both of us.
