UPDATE
Man what a BIG difference adding these skateboard wheels to the rear of the front seat frame rails. The 1.25 inch 50mm skateboard wheel lifted or titled the rear of the seats forward. the seat is actually near level instead of creating pinch point at the hips, knees and back. If you're happy with the seat just not the angle, try this skateboard wheel trick.. we did and I'll never have to use foam pads in the seat ever again.

Although difficult to see there is a 50mm 1.25inch skateboard wheel between the floor and the frame rail. I mistakenly purchased bolts that were too long, but used the extra cut in half wheels as washers.
