Searching for a needle in a haystack: SIS compatible top/aero mount boss
Searching for a top/aero mount downtube shifter boss that will accept SIS shifters. It does appear that shimano made such a device:

What bike is this for? Some mounts are different sizes. I recently purchased a gipiemme mount that doesn't actually fit on my bike's frame, it's too small. Both shimano and suntour top-mount shifters (friction-only style) fit. It's probably only 1.5mm too small, so not the end of the world to fix with a little creativity.

The Gipiemme seems to be for a particular mount that is sort of shaped like an anvil. I had to order from Europe for that trinket.
SunTour and Shimano seem to have different proprietary mounts as well.

This is for a Novara Randonee. I believe it was made by Nishiki.

I looked up pics of the Novara Randonee, and it looks like it came with these shifters around 1983. However, it uses the clamp-on version of these shifters, not mounted on a boss, so you are not restricted to using top mount shifters. You will still need to figure out how to get indexing from clamp-on shifters, but I think a Huret clamp-on shifter mount can be modified to accept Shimano index shifters.

Thanks. I have one of those problem solvers adapters already. I will likely use it if I can't come up with something more elegant.

Maybe I’m missing something, but if you want indexing, and you are going to a clamp on shifter, why not just go with a stock Shimano or Suntour index shifters in the clamp on version? Thereare plenty of those around and have had some myself in the past, 105s if I recall.

I want to use a pair of 10 speed DA shifters I have. I have modified a clamp for other SIS shifters in the past to do 10 speed, but would prefer to use the top mount boss if possible.

Got it. With the description of the part on VB and the age of the bike, I thought you were trying to run an older set up.

I believe there was a post years ago, OMG have I been wasting time here for 13 years already, where someone used a indexing stem shifter mount to cobble something nice looking together.
