I have eight of them. None of them are perfect. I'll sell them for $20 ea for the 2 best, $15 ea for the others.
I see them in worse condition on eBay selling for over $20 each. You can also buy an all plastic (replica) set of four for under $20 (shipped from China)
I have a few sets of the ones from China and sprayed them with clear-coat before I installed them and they have held up well.
If you are interested in the ones I have, I can show some detailed pictures and prices and you can pick what you want. Otherwise, I'll probably put them on eBay soon.
