It was a bit of a fiddle, but I wouldn't bother making a tool to do it; a little screwdriver could've helped.
I like the meaty Campag rear derailleurs, but they're damn expensive... about ten years ago I paid something like AU$80 for a pivot bolt and special little bush-type jigger to repair a $140 Veloce derailleur... but at least the parts were available.
