Interesting converstation with Year One, and they swear the twist was added to the spring because it takes the place of the pig tail to keep the spring from rotating, which it cant even with out the pig tail, because its an oval spring. Any, not worth fighting with them over a dollar or two, so call Jims auto parts, and they have both styles, and the twisted ones are much more expensive from them, but the ones with a pig tail a just a few bucks. So, this all makes wonder if Year one is crossing applications with this part, and its really for another style of brake lever and not all 11" drums. Why does rebuilding a car have to be a battle!!!!! hahahahahaha
