Wow, I am amazed at the trouble you are going to with this restoration Paul. But your dedication will pay off in the end. I must admit on one of my KXD-2 restorations the wheel stubs were actually worse than the ones in your photos. I decided to simply grind mine down until they could be re-sleeved with brass pipe. This saved having to cut them off and re-weld.

Interesting comments above about the ignition systems and engine.
