Review on Adjustable Backrest Touring Electra 2009 2020 by Mike Bucher

As you can see from other reviews, the documentation is very poor. Leaves a lot of guesswork to install it. The biggest issue I had to change was the base of the mount. You should bend it to better fit the shape of the wing. If you overtighten the wing bolts, I suspect that this will throw off the screw alignment and possibly bend the wing. I clamped it in a vise and bent it to match the angle of the wing. After the installation it worked great. I included it in the 2020 Street Glide Special.
