Got some photos.
I couldn't make the strap work well with the 2 piece seat and rectifier, so I just drilled some holes in the fender and bolted the bags to the fender with stainless bolts and acorn nuts.
I also put some aluminum strap inside the bag to help keep the proper shape, the bags were sagging into the fender bracket when empty. I have to get some acorn nuts to put over the ends of the screws....the aluminum bar was threaded for the screws.
I believe the later one piece seat works better with the bags and can allow the use of the center strap, as the fender for the 2 piece seat has a metal loop that blocks the path behind the rectifier. It might also have been better to drill and tap holes in the fender brace, and hang the bags from the fender brace in the manner that I have installed the aluminum bar inside the bags.
