All I can suggest is to call Jenson USA @1-888-880-3811..They had a special order thing going on their old web-site..Just maybe they can help..Jaybo said:I lost the rear R dust cover off my XO shifter. It must of blew off on top of the car. Of course, SRAM won't deal with me without me going through a dealer. The LBS in the PDX suck tail. Any online places that can get these parts?
