I recently went through this exercise in February - http://www.1130cc.com/forums/showthread.php?t=54497. I contacted over 200 dealers and was fortunate enough to acquire the second to last one in the US that I knew about through Lakeshore HD outside Chicago. MOCO supposedly has a new vendor and was to begin shipping these this month.

Called Harley on saturday and they told me the same thing they have been saying for a few months. Item is pending obsolete and not available, perhaps being discontinued. So if anyone knows how to order one of these parts or does, please let me know.
No drilling required. It fastens to existing bolt holes. I just installed one tonight. The wifey is happy as can be. I got her the Sundowner pillion seat. The cool part is that you can put the stock "passenger seat" back on relatively quickly when the wife is done riding. I've got the '07 VRSCX and the stock look is essential (when no wife is on board).
The need for speed: 1998 Formula Firebird (1998-current), 1998 CBR900RR (2001-2002), 2002 CBR954RR (2002, stolen), 2002 Hayabusa (2002-2004), 1998 VTR1000F(2005-2007), 2007 VRSCX #293 (current).
