I agree with the first responder, even the best fiberglass won't fit 100% and no two cars are the same. It will require some tweeking to get it to fit how you'd like but you'll love the end result.

As far as authenticity try and email or call rocket bunny themselves, write down the numbers you have on the fenders and they should be able to confirm that they are genuine rocket bunny products

I wouldn't be too worried about this though as you said before, you ordered it from a relatively reputable dealer so I don't think they would charge you rocket bunny prices and send you ebay type junk

There's too much risk for them as a company to be doing that.
