I have 5 old Craftsman routers, all work fine. For now. But if/when one dies I will either trash it, or keep it for parts. I won't buy a new one until all are dead.
If you have not yet tried ebay, I would say that is likely your best bet. However, if you can make parts, I would say try to find an owner's manual on line, should have a parts diagram, and may be sufficient to make parts. And it is always possible that later parts will fit. Best I can come up with. Good luck.

.....Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
