NECESSITY...is the Mother of Invention. Glad you had the fortitude, patience, and skills to attempt that modification. I will tear into anything but wouldn't have done that. I got my Ultimate Lowrider several years ago when they had a 1 time 20% off sale, and got the driver, driver backrest, and pass. pilion for $640. As a Christmas gift. I already had the Hondaline deluxe backrest for pass. and rear carrier. I have no doubt you will be able to fab a serviceable backrest for yourself. I offer the suggestion though, that you design a pivot to flip forward, or pulling the rigid bar out of the slot is going to get old real fast.
