Well I was not able to find the size of the bearings afterall. I thought I had written them down. Anyway I got replacement bearings (tapered roller) from Les Barker,. He is a great guy to do buisness with. His website is VINTAGEADVANTAGEMOTORCYCLES.COM. E-mail is vintrace@comcast.net. and phone# is (360)699-4964. he is ouit of Vancouver Washington. Just hit him up and tell him ehat you've got/need and he will hook you up. He does make the bearing kits himself. The bearing kit that you got that was the wrong size is probably for a 76 or later model. The 74 and 75 had a odd size only used for those two years (my understanding anyway) and due to low demand aftermarket companies just quit making them. I actually ended up with a bearing kit that did not fit also that came from All Balls before I found out about Les. Anyway good luck if there is anything else I can help out with don't hesitate ask. Jared.
