Geez, bgreenen, looks like your dog's been chewing on it!
Seriously though, welcome; and on your question, perhaps time to replace the router. You're going to be spending time and money trying to resuscitate a tool whose had it's day. In the meantime you're without the router.
Personally I'd have already decided on my new router. The old Craftsman would be in the recycling bin.

My Arithmetic might be wrong but if you've had it for 20yrs it's cost you $.02 a day!

Welcome to the forum.

One option would be to hardwire the router to run when power is applied, then mount this onto a router table w/ it's own front panel power switch, like shown in my router table topic. (Note, not possible for me to post a link until my post count exceeds 10, but it is in the Table-Mounted Routing forum.)

Another option is to contact a custom cable fabrication company. They make parts to-order, w/ specific ends and length that would work as a replacement for your application. The cost will be high, but those costs might be defrayed to have multiple copies fabricated, then sell those as replacement parts on-line for users in the same boat.

Or just junk it and buy a new router. Seriously? Why would you invest time, money, and energy in something that's well past it's 'Best Before Date'.
This is where the 'flogging a dead horse' expression comes from.
Not being cruel here; just trying to inject a dose of reality.
(OK...enough cliches.)

Good job...but you still need a new router.
