Steve, OK, I have 2 sets of extra rears. One set should be able to be cleaned and polished to get close to match the NOS ones you bought. The 2nd set is straight and good on the outside, but the inner edges show some wear (stones?) the inner edge where it screws in has 1/8 in deep wear. Hard to explain. Ideally, I would like to get a set of good original fronts so I can sell one good full set of originals. But we can talk.
