looking to replace the two bow rollers that the 64 kg Ultra anchor roll over, and seat into. Have contacted Ultra Anchors in Florida, they say the roller system is not theirs. Trying to source out new Delrin rollers, to replace the chipping, brittle, wobbly rollers. Ben of Selene Australia has contacted Candy on my behalf, and was told the sizing I need are not available. Anyone have any sources? I may have to turn a chunk of Delrin on a lathe :(
