Sb. in our club lost his original steel rims and has another set that he wants to have approved. Now he needs some official Ford sheet or brochure/data sheet, that shows the exact offset/backspace numbers of 65 and 66 4lug wheels 13" and 14" (66 would be enough). Have not found it in my 15 Mustang books nor Interchange manuals nor anything in my 3 binders. Might this be a g old card judges question?
