I ordered all 3 sizes of the brass flanged bushings from OldMiniBikes warehouse for the neck of my 1966 Lil Indian 400. The only one that will fit in the fork neck won't accomodate the size of the bolt. Is there a special size bushing? 1/2" x 5/8" Bronze Bushing,5/8" x 3/4" Bronze Bushing, and the5/8" x 5/8" Bronze Bushing are the sizes I have now. Thanks for your help.
