I wanted to switch to 14x5.5 steel wheels on the 70 road runner with dog dish hubcaps and after having them mounted on F-70-14 they were very noisy. I lifted the front of the car and they are dragging on the disc brake calipers which were from a later year A-Body swap. Were front discs available with steel wheels or do I need to go back to the rallies or 15" rims? What are your thoughts on a wheel adapter or spacer?
