Reason I ask, while I had the OD tranny out, I replaced the flywheel with a freshly machined one. It had a somewhat better condition ring gear already bolted on. I don't know the year of production of the replacement flywheel. Bolted the same starter back in, but when I try to start the engine, the starter clicks and whirrs, but doesn't engage. Jumped it with a good battery, seems to be a strong electrical current going in.
