I am in the process of rebuilding a 1982 atc 250r for a friend and am having trouble finding the bushing sleeves that go in the swingarm pivot. I was wondering if anybody might know of a place to get them or of another bike trike or quad that uses ones with simmaler dimensions. I know honda is good about using identical parts on newer models considering the 450r quad has identical dust caps and thrust bushings from what I have just discovered
