Okay, this is a silly question I guess, but I need to upgrade to 15" steel wheels, standard Ford 5 lug pattern. I want a 6" wide wheel with about 3 1/2" back spacing, or 4" BS if I can find them. All four need to be able to clear 11" disc brakes. What kind of Ford car would have these? I will be at the swap meet this coming Sunday and want to have a clue as to what I should look for. Are these super common or what?
