I purchased a Used CVO flhtcu last week with 8k on it from a dealer got it for 19k. all stock too. So i was missing the backrest. I had one on my 08 ultra i traded in but it was a mustang seat. Thius bike has heated seat so im leaving it on. I want the backrest that is supposed to go with it. I looked up the Comfort stitch backrest 52572-09a but the list says on fits flhtcu i dont think there is a difference between the flhtcuse7 and flhtcu on the backrest fitment. any ideas Jeff
