I have a Lunar 525 Freelancer with a red sway arrester type hitch it reduces the snaking/sway when heavy vehicles pass.
Has two securing bolts, one verticle, one horizontal which has hexican head and requires a hex wrench(Allen key type)
I need it replace the damper unit anyone any idea what the size of hexican wrench needed. Thanks

OK lads and lasse's panic ove have found one burried in my untidy garage, food for thought....clear it up.

According to the holder the hex( allen key sett) its 8mm for those who can't find information on this hex bolt. The newer versions hace Torqe heads and likely to be same size but only a guess, as the Torqe ones are 'Star' shaped.
