So I was at the local tire installer to have one of my older tires put back on the wheel. When they were done the tech guy came over and told me that when they were trying to get the center cap off, the plastic part of the center cap popped out! The wheel is a (Rays - Genome - Exon) I think they were only sold in Japan. I was looking on their website and could not find anything on replacement parts. Any help would be appreciated.
