It took a few iterations, but I was finally able to adjust all of the seat belt sections so that they would fit me nicely. I also cut a small slot in the bottom seat foam for the crotch strap. The straps came from Crow with plenty of extra nylon webbing. I basically have them cinched all the way down to the mounting brackets. The straps for the shoulder pads have about 6 feet of extra nylon webbing. I think I'm going to give them a trim later.
