Thanks for the advice men (I'll get to that) For now I've just removed the lunette, lots of water affected grease and a bit of rust (all-in-all) a bit of a mess) How much end float is acceptable with the lunette?
Cheers, Daryl
PS- just read the VicRoads doc Scott, chains "may be welded to the drawbar providing the weld encompasses at least 50% of the link and the following link is free to move" . Your suggestion may be legal. The chain length needs to prevent the drawbar from touching the ground. Food for thought, for the trips it'll do that may suffice
