Hi guys...

I was wondering if any of you knew where I could get some "H" center caps for those very same rims. I bought them for my Civic and would prefer to change the A's to H's. I don't know what size they are and I don't know what caps from other wheels will fit these, if any. People already suggested to look in a junker, but I don't think I'll find these too easily. Can anybody help?
Thanks.
