I should give ebay a little more credit, but both those websites go through their .ca addresses in canada. and amazon.ca, at least, has terrible selection compared to it's .com counterpart. either way, it's shipping that gets you up here, you never see free shipping that includes canada.
but I am worried about parts matching, I was under the impression I should buy replacement parts through the same factory if possible, and for all the shortcomings the vendor i'm looking at, they definitely have that going for them.
I've been thinking it over all night, by barely thinking about it and instead practicing some ring flattening and pondering tiny rivets, and come to the conclusion that I think is the most reasonable way to move forward. I'm going to buy the clutch service kit, and also one or two each of all the parts I absolutely know I need one of (the sprocket, the washer and bolt that hold it on, and the woodruff key) any of those parts that came in the kit are spares at that point.
ultimately i will try not replacing the shaft first, if that doesn't work i will replace it too.
as far as the bearings go, frankly, I am hitting my upper limit for budget this month. maybe in the future I will upgrade the factory ones, but as of now I need to get some miles out of the parts I have. I am hoping to get some traction on my chainmail making next month (which is fancy talk for go buy a small drill-press)
also, fatdaddy, I wanted to thank you for all the help you are giving me with this.
