Lincoln Town Cars of the 90s have stainless caps like BBS's They perfectly fit over the hex on an original hub cap. Tight on the sides and about an 1/8" gap on the inside of the top. I coated the sides of the style 5 originals with liquid nails and put a "glop" on the top of the original. Those caps can be bought on Ebay for around $90 per 4 and can be polished to a nice bright finish. A BMW logo center sticker available at the dealer and done. BBS stickers can also be bought on Ebay but they are little over designed and to me wouldn't fit the period look
