Hi, HC, You don't say what diameter downtube you have, nor how many cogs you want to be able to shift. If it is a "standard" 28.6mm clamp size then there are a number of alternatives.
I'm assuming that there is room on the downtube above the cable stops for you to attach a clamp-on shifter. Then you can just run the cable through the holes in the cable stops. I don't think that putting the clamp below the cable stops would work so well because the shifter will get held up by the cable stop and not be able to shift to the "last" gear. If you're shifting 5, 6, or 7 cogs, then you can go on EBay and find yourself the relevant used or NOS clamp-on shifter for your derailleur pretty easily. If you're trying to shift 8 or 9 cogs, then one strategy is to get a Huret clamp that has been modified to work with Dura-Ace downtube shifters from a guy who sells these clamps on EBay, search on item *170599854261. *Another strategy is to get crappy SunRace 7-speed downtube shifters and use the clamp for those with your Dura-Ace downtube shifters.
