I was planning on switching my 1972 honda cb350 forks with a 1968-71 fork because I like the look of the external spring. I already have to buy a new triple for the forks because mine was cracked. I think the fork size on the 68-71 forks is 33mm but it could be 35mm. Also I began to wonder if the hub from my cb350, the 72 would fit on my new 1968-1971 forks or if I should just do a full front end conversion. The rims that will be drilled are very expensive and I would prefer to not mess that up. I was planning on having Dime City drill 36 spoke Aluminum Excel rims for my current hubs. I heard someone say the C to C joint was different. Any Ideas?
