I have a 67 Formula S with Kelsey Hayes front disc brakes (sbp). Was told that a 14 x 6 Ralley wheel with a 4" backspace would fit. It does not. I've read replacing front studs with longer ones and adding a wheel spacer is a way to fit the wheel and I also read grinding down the caliper. In the future I may replace the brakes, but looking for a fix that will mount my new wheels. Thanks!
