I have a couple of photos in photo bucket of how I am doing my seat belts (lap only)in a 46 Art Deco. The cab has a second set of holes at the rear mounts. I used 7/16in grade 8 bolts with a fender washer underneith. I spaced the angle above the cab mounting springs with pipe. I used a 3/16 in 2by2 angle iron. I bolted the seat belts with grade 8 bolts to the angle.
