Anthony: I see you jumped right in there. I posted this as wanting to buy something - not wanting to start an auction for something. According to your profile you don't even own a 919, so why would you be interested in a component for a seat without a bike? It is certainly possible that you just don't have an updated profile, if you are intersted as well and have a 919 with a Corbin seat (and no backrest). There might be a better way of finding one instead of butting in and jumping the gun. I may be just getting a bit hesitant when people are trying to do business over the net like this while they are getting banned from the forum.
