Thats correct, it's according to serial numbers listed for the part changed.
The earlier covers were one solid piece with a small clutch inspection cover. If you weren’t a contortionist and needed to work on the clutch, you had to remove the fuel tank, disconnect linkage and remove the entire top cover. The later models had a small inspection cover and a large clutch cover that was fairly easy to remove.
Thanks for the responses. After initially not being able to adjust the main clutch to the point where the throw out worked, I applied a little extra elbow grease and obtained sufficient rotation of the adjusting collar to get a good clutch lock. No need to replace the clutch plate at this time.
