I cannot see any reason why you could not use these in most radios. As long as the pots are 5K on your other sets. The only oddball I ever came across was one of the early Saturn radios, which had 50K pots, a bit weird.
As long as you can physically get the sticks installed, all you would need to do is hook up the centre wire from the od pot to the new pot, and the other, outer wires to either outer wire on the new pot. Sounds easy, but may be best to practice on a cheap, old two channel set first, just to get the feel for what is involved.
