How did you get th ZL center caps. I have a SLP ZL585 and SLP does not sell anything with the ZL on it without bring the whole package. Even to a owner like me. True SLP rims are grey and have the red rim. These appear to be Similar but not SLP. Don't get me wrong, love them and they look great. Nice ride, I am enveyous because I want another set of center caps and can't get them. Please share how u got them! Email me at emotive@ comcast. Net if you don't want to share with the world.
