I ordered a black aluminum version from wingstuff.. the one I received had obviously been used before, so i called and they shipped me a new one and return shipping.. but

a couple of things:

1) installing this was a lot harder than it should have been. The unit I purchased had TOO much length on the smaller front piece. I had to push it way past the natural bend that should line up with the front plastic. To get the second screw set, it took a timing mirror and two people with a LOT of force before I could get the screw holes to line up. I am NOT looking forward to changing the oil. I may get some tin-snips or find a way to cut it more to length. I am not happy with the manufacturing of this unit

2) OMG.. did it seriously cut-down on side-wind impact. I don't understand why these aren't part of the stock, they make a huge difference.

just my $0.02
