I have never seen one listed.
Also, to eliminate confusion I may have caused, the problem is not in shifting to/from the small chainring but rather shifting onto my large (52 T) chainring. My reference to the 3 mm clearance between small chainring and chain stay was to indicate that it may not be possible to use a shorter spindle to get proper chainline.
If no solution can be found, I may just end up using the large chainring as a "chainring protector" and adjust the FD to eliminate its use.
I understood that the problem was getting to the large ring with a double FD that doesn't move out that far.
The "period correct" solution to your problem is either using a period correct TA "compact" crank with two smallish rings, or a period non-Campy front derailleur.
I get that you are trying to keep the bike period, but you just installed a triplizer and a new RD cage, so maybe you should get more flexible about other components rather than having a useless outer ring. What would someone in 1974 have done?
