I've been thinking about these parts - and I suspect I could machine them, or at least something close enough - that would work as intended. It would require building some fixturing to do so on manual machines, which are all I've got.
That said, I really don't think it's economical in terms of time; if there were none on the surface of the planet, yes - but if there's some of the original parts out there to be purchased I suspect they would be the right way to go.
As for just hacking something together, I've been an engineer far too long to do that. If this were an emergency where I had to keep a generator running, I might just make-do, but that's not the case here. I've owned too many things in the past where I've had to make right such field repairs that were done by someone that didn't think about the next poor SOB that might want to keep the unit running. In those cases, about half the time of the repair is spent making new parts to replace the original missing ones, and the other half repairing the damage that was done to the base equipment by operating with a less than optimal field repair.
