So, I stumbled upon a set of Dia-Compe 980 canti brakes at a co-op a few days ago. They are exactly the style that I am looking for, but to my dismay they require a very unique spring. I've looked online but have not been able to find any springs with that little arm that sticks out like I need. Are there any websites that you guys know of that has those little unique pieces or am I reduced to either getting a different set of brakes or searching the bottom of cantilever piles at bike co-ops forever?
Some pictures:
This picture is the best one I can find that shows what the spring looks like.
