Sissy bar & Back Rest to work on KZ1000P frame.

I recently modified a 92 KZ1000P Police Motor into what I call a Cruiser. I mounted a Kaw Vulcan rear seat, but was wanting to get a Sissy Bar with Back Rest for the wife. Has anyone done this on a KZ1000P? I was thinking of buying one of ebay and then if I had to bend it closer together if too wide or spread it apart if too narrow. I really would like something that I can remove and put back on when riding double. Any ideas? Thanks.
