Is the reason you want to replace those springs because they have stretched and opened at the ends? I'd just cut off the section that stretch then use a decent pair of side-cutters to squeeze between a couple of the loops in the spring and then without actually cutting into the spring twist those two loops so that they are 90 degrees to the rest of the spring. It's what you'd have to do to each end of a door spring if you bought new door springs anyway. Also, I put a brass S-hook onto each of the springs on my two panniers I put door springs onto. I hook the S-hook to the rack leg.

If you need help let me know and I'll take images of the method I use to make the springs fit my pannier and will post those images for you.

Cheers
