I have a 9" ford rear in my 40 ford p/u with 5.5 " pattern and a 4.5" lug pattern on the Mustang II front end. I want to carry only 1 spare. I don't want to use wheel adapters . Can the rear axle be re-lugged to a 4.5 pattern and if so than what can be done with the brake drums ? Can they also be re-patterned ? Or who sells drums with 4.5" pattern ? thanks for the inputs !
