Well i got the part back last week and made an arm to go across the frame to put the hitch on the bike and today silly me didn't hear that the nut came off and the hitch did too. Its somewhere in the rain and i just can't retrace my steps or cycling to go find it. The rain is way too heavy....so i googled and this is what it looks like http://www.amazon.com/Coupler-Attach.../dp/B0013TR66I . Anyway so i have to start again now and see what else :0( Does anyonme know where i can get the same hitch as i am not finding anyone on ebay that sells them or in australia. Amazon.com don't seel most things to us in australia i found out. I don't know why!
