Dia Compe canti spring- How can I replace?

Bent this one out of shape and can't seem to get it back to form. Are replacements available?

And while we're at it- any advice for getting the springs to sit flush on the posts? I tried turning the spring to make it constrict hoping it would pop into place but this did not do t the trick.

Look on the eBay- I searched 'vintage diacompe cantilever brake spring'-you can take a $10 gamble that the spring is the same on a DC980 vs a 983. Or buy a new set of 983s. Or take the opportunity to get some fancier brakes.

or spend a few minutes admiring the "reissued" 980s that Rivendell have on their site, which (apart from taking threaded pads) have got to be some of the tastiest-looking cantis one could ever wish for.

Seeing as how those look a lot like the Tektro CR720 with the adjustment slot farther from the pivot point- they may be designed around a modern bike with modern canti spacing. In other words- they may not work on a "vintage" bike with narrower spacing.
