Ran into this a few weeks ago when I added bar end shifters to my '84 Supercourse. After reading few threads saying it's possible to modify Shimano cable stops by grinding out a notch to accommodate the braze on. I tried doing this with a Dremal. I'm usually pretty handy with stuff like this, but it didn't work out for me. Maybe I had the wrong type of cable stops to begin with.
My Raleigh, and I believe your kodiac came with a flick stand that doubles as a cable stop on bikes equipped with stem shifters.
This is what I'm doing for now. Not real happy with how it looks, but it's functional.
Edit: Of course, if you don't have the plastic piece for the flick stand. This information is useless.
