If you're looking for alternatives to the OEM units, I think you'll be out of luck unless you can fabricate your own or know someone who can fabricate something suitable.
And if you're after a set of OEM footpegs (which I believe come as part of the passenger seat kit and know they interact with the on-board computers to vary traction control, yaw sensor feedback, and other 'Nanny intervention ) then you'll probably either need to go to/thru a dealer for new gear or for previously owned gear you'd likely be better off putting a WTB: advert in the 'For Sale by Owner's' section of the Forum. I can move your thread there if that's what you're after.
Still, I don't really like your chances of getting them second-hand tho, but you never know?!?
