I just posted this in the Black market but thought I would give it a shot here...
I need the center cap and nut that goes with an older style RH C5.. Any thoughts??? Damn tire shop cant get the thing off and I have gone through two of the plastic keys they give you. It has come to the point of using vise grips to get it off and scrach it to hell. You all seem to have the best info around so I thought I would give it a chance...

Anyone that can help I would truly be thankful....

Thanks
