Someone mentioned about installing cable adjusters...that's what I'll probably do to the SS I'm building. I have a Bianchi that was downtube shift and that I recently converted to Campy 9spd Ergo shifters. The downtube shifters were removed and Campy cable adjusters installed in their place. The cable adjusters are a black plastic cover with screw that attached to the boss and has a hole for the adjuster. You could just leave the adjuster and spring off and at least the covers would look nicer than the bosses (and less likely to remove skin if it came in contact...). Shimano has an equivalent that is silver. See at link below:
