Did Campy make a triple specific Record derailleur in the mid-70's? 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.
