It's good to hear that these parts should be of some use. The teeth on the gears seem to be OK. Some of the surfaces on other parts might need some light sanding or other work down the road.
The rear pulley will be interesting once I get everything apart. I had to order a socket so I can remove the big nut (I used to have one but must have lost or sold it at some point), but there's clearly a decent amount of rust back there too.
The flywheel had its own rust, but I was able to get most of it to go away too.
