Shifter Mount Question

I’m stuck on upgrading an older 80’s touring frame with a STI shifter. This nishiki cresta has a mount that I’m not familiar with, just one braze-on on the top of the downtube. The braze-on is barely visible on the pictures below. I think it’s for an older suntour shifter, I think it was the shifter that would auto trim the front derailleur. I can’t figure out how to mount the housing stop. Is there an easy solution that’s escaping me?

Sine that looks to me like a standard size steel down tube, try Loose Screws or Harris Cyclery for a clamp on cable stop.

I was thinking about one of those but do they hold well. I guess I'm concerned about one slipping and degrading the shifting.

No problem. Install it just above the old top tube lever mount.

The purpose of the piece on the top of the downtube is to stop the clamp-on shifters sliding down.

No, the OP had it right. It's a mounting boss for a "downtube" shifter type used by Sun Tour that mounted both shift levers on a single boss.

The stops intended to keep band-on shifters from slipping were much thinner and brazed on under the downtube, not on top.

I have the same exact problem currently. Let me know if you find anything, otherwise I'm just trying to find a nice cap for the mount and going to use a band on the downtube in front of the shifter boss.

Same bike, same problem. I haven't been able to locate the SunTour mount. I'm considering trying to make my own bracket using a set of clamp on bosses and some aluminum plate, but I want something that looks nice. If it doesn't work out, I think I'll mount the bosses higher up the tube (they'll just be holding adjuster barrels, I'm using bar-end shifters) and try to come up with some utilitarian purpose for the single bolt. Perhaps it will be a good place for the pepper spray or a side-throw light?

seely/Cynikal--How do you like your Crestas? Mine hasn't been built up yet and I'm getting excited--I'm trying to have mine touring-ready by May 19!
