You can try The HD dealer on Northern Blvd, in Long Island City. I used to get parts from there. They changed out my rubber once. I did/do most of my service myself though. They didn't have race stands though so be be sure to mention it if you have a pipe without the internal supports. Frankie, one of the service guys that looked like Tommy Chong was pretty cool but claimed he never heard of the mods i was describing. I think the Service Manager (younger guy rode sport bikes) was able to spot some of them without being told. This was a few years back though like 2011/12.
