For sale is a used set of Pit Bull trailer restraint pins. Part # F0075AA--001 According to Pit Bull's site, these pins should fit the following: GSXR1000 '01-'08 Hayabusa '99-'11 GSXR600 '97-'05 GSXR750 '00-'05 There is nothing wrong with them - I simply bought a different bike requiring different pins. These retail for $80 but you can have these for $60 shipped.
