Aftermarket Floorboard Bracket

I'm not sure where to start. I am looking for an aftermarket part that was available through JC Whitney. Whitney has discontinued the part but referred me to Big Bike Parts/Show Chrome, which also proved to be a dead-end. The part was included in a "Deluxe Custom-Fit Bolt-On Mounting Kit", JC Whitney number was ZX010701B. According to Whitney, the Show Chrome number was 21-431W. The part I need fastens to the 2001 Valkyrie's original drivers footpeg bracket on one end and to an aftermarket floorboard mounting bracket on the other. This is my first step in trying to locate someone who may have one (or more). Can you help and/or guide me?

Thank you,
