So the story...I got a Ultimate 4 piece used. It came with a sissy pad. The sissy pad had a hole pattern that was not standard to any market sissy bar. NEAT! So I had a buddy who does metal fabrication (really, near anything you can think of from cast iron to bike parts to medieval armour) make this for me. A trip to the chromer, and viola, my wife is comfortable on the back of my bike.
