This is a seemingly random question but I recall my B5.5 having black wheel bolts and black lock bolts (the version where the key is a multi-faceted star vs. what is being sold today). I received a set of what was described as OEM VW branded lock bolts (same multi-faceted star) in silver with appropriate VW bolts caps. Just wondering if they were ever available in silver and if they changed from black to silver at some point. Want to confirm what I have is OEM. Thanks!
