Attach the upper frame bracket and upper spacer [ITEM B] to the upper T-bracket using two 3/8-16 X 7/8″ flat head cap-screws [ITEM J] and secure tightly. Ensure you orientate the upper frame bracket with the two vertical flanges outside the frame toward the wheel.

Then attach the assembly to the underside of the SumoSpring [ITEM A] using a 3/8-16 X 5/8″ flat head cap-screw.
