Does anybody know what size 5 lug steel wheel will fit an 11" caliper and rotor for disc brakes on the front?
A GM 1/2 ton 2WD pickup wheel from early '70's to at least '99 should clear. They are 15", same lug pattern, 5 on 5. They can be found in 6, 7, and 8" widths. Not sure what Cadillac wheel covers they will accept, but it should get you rolling.
Perfect. Thank you very much for taking the time to answer. This cuts to the chase.
