So, I'm finally back working on this thing. It has changed quite a bit. But still the same issue with the tires. I assume with Ford's stated spec of 0 offset equals 3.5 -4 " back spacing on 7-8" wheels. I cannot seem to find wheels with LESS backspace. Went to 4 wheel parts in Redondo Beach. They went full bore to sell me wheels with 4.25" backspace, saying it would solve the issue. When I told them, OK, but if the tires still rub on the front leaf spring, I won't want to pay. Then they said they have no way to guarantee that. My initial search for wheels seems they mostly have stock offsets and backspacing.
If someone can point me to the right place to buy the new wheels, I would be greatly obliged.
