P.S. Just ordered the waterproof seat covering from Cary as well. I have a Jac Vinson backrest and Cary warned me that it might not fit since it was cut for other brands of backrests but I decided to take a chance anyway since we are approaching the rainy season here. It is a tight fit but with some maneuvering it fits and does the job.Fulton Williams said:Yup! I ride on one of Cary's seats as well. Best after market add on I have invested in!
