Can anyone identify this rim on the right? Both came off a 60's Ford truck. The one on the left is the typical KH 15" 5 on 5.5" x5"w. The one on the right is 15" but its 6" wide and there are no provisions for a small hubcap. No springs or nubs. I'd like to find a match to it but not sure where to look. I could not find another like it among the three early 60's Ford trucks this wrecking yard had.
