I purchased a set of appliance spoke rims for a 1983 Cadillac Eldorado. The original center caps are about 5 1/2 inches in cir***ference. They are extremely hard to find and if you do find them they are ridiculously expensive. Essentially for four center caps I could buy a set of average rims. Does anyone know of a Cadillac center cap or any other plain center cap that would fit on an appliance spoke rim. I have no problem purchasing an aftermarket Cadillac crest sticker and putting it on. I just don’t feel like spending $500 for four plastic center caps. Thank you.
