Trying to find CL77 rear sprocket and drive chain

[RetroBiker]

Does anyone know where I can obtain a new 40T rear drive sprocket and 100 link drive chain? I hate to ask, but I've come up empty on Ebay and my Honda Parts Book does not list the part numbers for my 1966 CL77. Thanks for your help.

The chain should be easy to replace. I bought one at a local repair shop. It's a standard chain and they knew what I needed when they saw the old one. I can offer no help on getting a new sprocket. They can be custom made but it's a bit expensive.
