my local dealer didn't have anything when I went in - nor a part number to give me, so I had ordered what I thought was the one for our K13's - the CF10709 (I believe that was posted here at some point) - thing was far too ridgid to be bent through the half sized hole so I just ripped off the two end plates allowing it to accordion down, and it sprung back up to size on the other side :P $12US from amazon I believe.
