Cragar Mach 8 Spacers

Yeah, the ford guys were saying that people ran them without the spacer, but they always came loose. Apparently the ring is just to hold the washers in the correct position. They were saying that people ran the washers without the ring, but ruined alot of them because they rotated too easily. They recommend gluing the washers in place if you don't use the ring.
Seems pretty cheap to me. Cragar should have just made the wheel for individual applications.

Exactly. You cannot run without the ring washers......even if the wheel fit the lug pattern. Look how the recessed area would not be flat against the wheel. As you tighten down the lug nuts, that recessed area would crush and break, since it has no support from behind there. Disaster.
