I don't know if they'd fit your model Dyna but Harley lowered the price on the passenger peg mounts for my bike (09 fxdb), they were 120 when I first priced them, went to buy them a few months later and they're now half that price. Check the accessories section on the harley website and you'll see them, if people are actually paying 120 for these things on ebay sounds like there's money to be made there.

 

I tried to search but couldn't find them so I found them by part number (saved my old receipt, they were $69.95). Good luck. Also watch out for that one damn front bolt on the belt guard, that thing is a bitch.

part # 50210-06
