The BRS Mount turned out really well, very solid. I did not paint it or add a finish mainly because it is hidden behind the baggage area. The mounting system consists of two pieces the main mount and the stiffner. I will add the back side photo of the BRS mount which is effectively 6061 .050 with stiffners and backing plates, secured with 3/16 aluminum rivets and cold weld. (didn't have any Hysol on hand) and of course a generous amount of WDG-7 Adel Clamps. the Stiffners added to the main assembly are courteous of the Hardware store-channel and the 1"x1"x1/16" angle.
I added the truss or stiffner piece mainly do to the length of the frame tube the mount is secured to. wasn't bad this is better. I used the framing tubes in the baggage area and the baggage floor pan. the floor pan is used mainly for lateral support not much weight bearing here. all three connections give it a very solid mount. Overall very happy with it. Does bother me a little I didn't powder coat the assembly but I will get over it.
