I have a 1965 Mustang. I am upgrading to 5 lug wheels when I upgrade the brakes. The old 5 lug wheels are 5 (4 1/2) bolt pattern. I was looking at the new Mustang wheels and they are the same. Someone told me the new wheels wont bolt on to old Mustang, why? Is this true? They seem to be the same bolt pattern, can someone explain?
