Cragar S/S ID

Well then I have no clue for what other reason Cragar would use 14" centers with 15" rims. But that's what you're looking at.
Cragar did that with the 15" small bolt wheels they make now. They only make 1 center for those wheels. The Uni lug wheels in your photo are 4 1/2-4 3/4" bolt circle.
