If I were you, I'd make one that either attaches to the bottom of the seat pan and comes out between the two seat pieces or one that attaches to the fender rail. Definitely wouldn't pay mustang for it. I can't justify that kind of expense for a bike that only cost me $5k.
It's a Mustang, and I am certain it would fit. I love it, but I REALLY want the one with the driver backrest...which is about $200 MORE expensive. Guess I will just suffer a while longer!
Thanks! It's a 2009 Shadow Aero. 750. Other than a few cosmetic changes, it's pretty much the same as your bike. So.....I wonder if that seat on yours would fit mine....
