Never would have thought a Kia rim would fit a ford mustang but I guess there are only so many stud pattern combinations. The Kia option opens up a whole new search area
I have recently restored 71 Mach 1 back to original . 351C 4V with factory air. It is in body shop being painted this week. I am missing the space saver spare tire , jack and lug nut wrench. I have heard that a space saver from a Crown Victoria, Lincoln or Marquis would fit , any idea what years?
