You are right about ebay. I went on last week on a fluke, and found a NOS Honda lower guide sprocket (roller assembly) complete! It was pricy, but I knew that they were very hard to find, and I bought it immediately.
I hope to be able to find the slipper and the upper roller. Does the upper roller have teeth like the lower one?

The pistons did touch the intake valves, and may have bent one or both of them, so I will have to address that as well, but the piston was not damaged, so I suspect that it only collided while we were turning the engine over carefully by hand.
