Get ready to taste the flames baby! Just kidding... can I ask why you want to install shifter bosses instead of using clamp on down tube shifters?

Hmmm... first I assume that you are going to use it in friction mode since you all mixing Suntour and Shimano?
If thats the case you could use any clamp on friction shifters that you can find. I think the Shimano ones could potentially be a problem because they work with a different shaped boss.
One other problem with a clamp on is the potential for it to slip on the down tube so you will want to take that into consideration.

Oh, I understand now.
I realize this may not be what you are looking for, but it is an option. Rivendell sells bar end shift pods that you can mount your RSX levers onto. https://www.rivbike.com/products/list...product=17-068

The frame is not too old. The stem shifter setup should, like barcons, have a downtube cable stop in or near the location of downtube shifters, right? Since that's not brazed on, it is clamp-on, and there should be a stop of some sort on the underside of the downtube. That should prevent the clamp-on shifters from slipping down the down tube.

Barcons would be the simplest upgrade.
