Very hard to find center caps for the alloy wheels on 1979-85 Cadillacs.  I am uncertain on the years these fit so please verify before bidding.  The total diameter of the caps is 9" while the diameter where it snaps on to the wheel is 8".  One is extremely nice with some light scratches.  The other has a larger scuff on it from brushing a curb, but the cap is still very straight, and I am quite certain the stainless can be polished to get the scratches out.  See photos.
