Greetings and Happy New Year!
I have a mid/late 70's Cyclone rear derailleur that I am itching to use on my 1974 Nishiki Pro. The original rear had a too short a cage for the wider gearing I'd like to use. Anyway, I've gone and overtightened my #11 seen in both images in the link below. Stretched it like taffy.

Any ideas where to look? Loose Screws doesn't seem to have one.
