Hey guys, my family (specially my dad and both granddads) have been begging me to keep my rally rims, I don't want them on my car because they don't go with my theme....but to keep them happy I will keep them and use them for track use only. The rims are in good shape, but the cap is not...yes, one cap. Here it is 2 questions 1. What would be the best way to restore this? that black stuff is not dirt, it's missing chrome 2. Where can I buy 3 more authentic caps? From what I was told when the car was bought, they were stolen (why didn't they just take all 4?) I understand these will be very expensive. This is very low on my priority list since they won't be used often, but I'd like to keep an eye out for them.
