I know one or two of you out there have Work Wheels. I have some Work Meister S2R's and some how some way I lost one of the center caps. In looking for a replacement I found the only place I could get one was from Work Wheels as these wheels have been discontinued. So I ordered a new center cap from them for $35. Got the new cap to find it was the wrong cap. The problem being my center caps thread on and the one they sent snaps on. Not only that but the color doesn't match. The cap I got wont snap on into my threaded wheel and I didn't want to break it trying. I called Work Wheels and talked to this guy Jim. He says my wheels are extremely rare and only made for about 9 months in the early 90's. Since I bought the car with the wheels on it I can't exactly argue with him. So I'm asking for any help or any suggestions you guys might have.
