seems to be a secret as I can't find them..

Bueller??? Bueller??

Call IMCO and talk to Ron. He will have it. They supply it with their kits, so I'm sure he will sell it seperately. I looked but I couldn't find a part # for just that part.

Thanks ED!

I have one I got from IMCO and never used. Are you just looking for one to conceal under the wheel hub or are you looking for a bling one? I think I paid about $115 for it. I'll give you a better deal than that. BTW, it is not a stainless bling piece. I can dig it out and snap a pic if you are interested.
