Thanks for the responses to Off-the-Wall 1.0. I really appreciate it.
Next:
(a) My rear valance ('67 FB) is sprung at the bottom. There is 3/4 in. space between valance and lower rear fender. There appears to be a threaded shaft inside of each side but I don't see what it fastens to.
(b) Going by pictures, the front and rear bumper hardware in the catalogs seem like thin stampings. If I ever need the bumpers, I want them to protect my body work (and my brittle, old bones). Used, original pieces (rusty but salvagable) cost the same as new pieces from the usual Mustang suppliers. I don't much care what they look like. Would I be better off cleaning and painting some originals?
Thanks again,
