Tube shifter mount options?
I have a mid-80s road bike frame, and prefer to run handlebar shifters. Are there any creative options anyone can suggest to put on the tube shifter mounts aside from just a cap? I tried doing some Google and Etsy searches, but I must not be using the right keywords.
I'm thinking of possibly getting them removed at the local metal shop since I got the frame sand blasted, and it's now or never... that is unless someone has a decent suggestion, because I'd rather not.
I'd attach a photo, but I don't have 10 posts yet
Thanks in advance!

Give us some hints. Bike model and year. Brand of derailleurs and shifters. There are cable housing stops that mount on down tube shift bosses. If these can be had for your bike, an easy fix. (Not totally perfect. The housings will bang the head tube and do a number on the paint. There are fixes and thousands have just lived with it.

I have wondered about this solution as well to unused downtube shifter bosses, though in this case it was due to running Shimano Di2 electronic shifting.
If you are planning on running handlebar shifters, KEEP THE DOWNTUBE BOSSES! Handlebar shifters will run their cables to those bosses (via a downtube cable stop) which will then run to the derailleurs. The cable stops also have provisions to add or release cable tension--another great tool for tuning your shifting.
The cable stops will look like this, generally. They are also pretty cheap and still available.

When STI first came out, the upgrade kits all came with these things.
Lots of suppliers if you use the right key words.

I'm an outlier. I've had one bike in all my years with DT bosses and didn't care for them. Much, much prefer the clean under the DT simple plate stop for a clamp. Ordered that for the Mooney, used the clamp-on SunTour shifters I already had, then moved to the SunTours that sit on the box on top of the DT after it came out. My geared TiCycles came with the HT braze-ons which are still sitting there unused and a mount for the Superbe shifters in that box. Bike is now fix gear with a wonderfully clean DT.
That simple plate boss/stop? Clean, invisible when not in use, versatile as heck and never snags expensive tights. (Light, aero, cheap, strong and reliable - I thought that was impossible in the world of bicycle reality.)

I really wish there was a better option for the bosses rather than a cable stop or a cap. Looks more than likely that I'll be getting them removed, and ordering some cable stops from FrameBuilder to match very similarly what RiddleOfSteel posted. It has me thinking of doing the same with the rear brake line to clean things up while I'm at it.
Anyway, thanks all for the input and advice! I definitely learned a bit. I'll be starting a build thread when I get past the 10 post mark. I'm feeling pretty excited about where I'm taking this bit by bit.

Not sure that I understand the concern, but if I do, I solved that little problem years ago. Though Mr. Mouse, some people just call him Micky, suggested just putting an inner tube valve cover over the mount. I do not have a picture of this (actually, I probably do but it is a PAIN to find) but you get the idea...

The Problem Solver caps work well to keep the sharp edges away from your pants though, so that's useful.
