As long as you can fabricate a fixture to support the pedal assembly, the S-10 pedals should work. When I was building round trackers I used 1" square steel tubing to fabricate pedal mounts. Scavenge the pedals and the pivot shaft from a donor vehicle and fab your own support brackets. Square tubing is strong, and easy to cut and weld to make a custom-fit support.
