Providing they are not something bizarre - completely available. Most
of those rotary switches are modular (they can be bought as parts), so
the exact switch can be reproduced.

Probably. Most vintage connectors, in general, are still available. If
I could see a picture of what the connectors on ENIAC look like, I
could tell you. I seem to remember them being pretty standard Cinch
Jones parts.
