I have 4 very good condition 15" moon discs for sale. I used them for about 2 months in my previous car and then I took them off and sold the car.
You can see on the picures, that I made a holes for valve vents. After drilling a second disc my drill bit got dull and I gave up. Those hub caps are made out of stainless steel and they are really hard to drill.
I'm asking $40 including shipping.
