Good morning! I have had problems finding a fit for mag wheels on my 1965 Thunderbird. I have skirts on the rear with drum brakes and disc brakes on the front. I ordered a set of wheels in that were supposed to fit but they fit on the rear and hit the disc caliper on the front. Can anyone advise on the wheel offset needed for my application on the front and the back? Would prefer to keep 15" wheels but open to change if I find something that looks nice and fits in a different size. Thanks for your help!
