a. Loop one end of chain through a U-bolt. Run hex nuts all the way up the U-bolt to give extra support before

installing the U-bolt to the seat assembly. Drill two holes (approximately 1 1/2 inches) from the top of the seat riser (using

1/4 inch drill). Mount U-bolt to seat assembly, tighten nuts and stake threads (on inside side of seat assembly), so U-bolts

cannot be removed (Fig. 7).
