When I started the body and paint I wanted to go with the early 710 bumpers and couldn't find any, so on a trip to the wrecking yard I ran across a 1973 dodge colt (Mitsubishi Lancer). The front is welded on to the shortened stock bumper struts, the rear bolts right on to the body with four nuts and bolts. We had to widen the rear bumper about a half inch.
