I have one of these, a bike carrier from the US which I would like to use..
http://www.ebay.co.uk/itm/Swagman-64095 ... 28059acda4" onclick="window.open(this.href);return false;
My carrier however, has a square hitch bolted on, with a large pin which locks.. for a US square hitch towbar.... the one in the listing doesn't have that hitch on - but you can see the bolt..
is there anyway I can attach it to the my tow bar assembly? I don't mind unbolting my tow ball when I want to use the rack.
Not sure if that makes much sense
