I have a 1965 3.3 L ford mustang with 4 lug... I currently have 13'' and would like to go to 14 or 15s. I am thinking to stay with 4 lug but I have probs with all drums... I am wanting to change to 5 lug all disc to make tire finding and stopping capabilty easier and better...where can i go to find some wheels in 4 lug?
