Ya Art, you are in good hands. Thats the correct part, I just had to get one myself for the same reason
It is the same primary parts as a Sporty, the engine case was just made with one less cylinder!
FYI, I was able to wiggle the shift shaft out without removing the clutch basket, maybe you get lucky too? The adjustment with the .0187 (IIRC) drill bit will be hard to do like that, but that just centers the pawl around the shift drum and could be done by eye if you don't have a crank locking tool.
Hope that helps
