Well, sto and Greg got it and sounded happy with it so I thought I'd give it a try. First, I was a little skeptical about a cover over the existing cap, sounded cheap. One thing you should know is, it is not metal. It is plsatic, painted silver with a clear coat. It looks very nice though. The black hex screws around it look real. Here's the top, looks nice!
Here's a pic of the bottom. They really did a lot to ensure it holds tight to the stock cap.
When you put it together, it covers the black cap. It's not like a sticker on the cap or something like that.
I just wanted to provide this info for anyone who was thinking about it but like me was scared it was a cheap sticker that went on the top of the old cap. -JoeB
