The 15 definitely has contact fingers at the bottom that hopefully match the keyboard.  I have to dig up the 15, it's in a box on some pallet on some rack somewhere in the warehouse:-). Over time I've gotten smart enough to not just plug in new old stuff, too many clouds of smoke.

But from what you guys tell me, I'm getting optimistic.

As I was playing with the keyboard, I noticed that the 2 toothed gears (that are separate when no key has been pressed) are slightly touching, causing a grind noise.  Just the tips are touching.  I assume that's not good?

I essentially did this, but that was 64 years ago.  Worst problem I had
was with the cover.  The normal 15 cover doesn't have some of the
cutouts needed to clear the PEX (actual name of the 19 keyboard.)  Which
version do you have, character counter on right or left?  Right side
would require less modifications to the cabinet. I don't think there is
any difference in bases between the KSR and RO.  If the 15 was RO it
maybe doesn't have the cable for getting 120 VDC into the base for the
tape punch (you need about 80 mA of DC for the punch if I recall correctly.)
