I have a 2003 Shadow Sabre 1100 (VT1100C2). I have a bad back and I could really use a backrest for my bike. The Protac driver backrest would be perfect but I can't seem to find one anywhere. If you know where I can find one or if you have one that you wouldn't mind selling, or if you know of another alternative, I would really appreciate it. I cannot afford the $800+ Mustang seat with backrest (wish that I could).

Thank you!
