DP CF Gas Cap

I have bought and installed many DP parts, some CF. All have been of good fit, finish, and quality. But not so with the CF gas cap. The finish is of good quality but the fit is poor and the hinge mechanism does not look to me like it will hold up. Also the cap ring bolts are easy to round out, they appear to be soft aluminum. Rigt now I have it installed but to get it to lock and seal on the tank I had to loosen the bolts on the lock mechnism. The worst part is you have to modify the stock base by filing off a tab that provides for venting, so now I cannot go back to stock without oredering a new base. Just wanted to pass this on.
