So I took off that spring it's known as an elongated spring which I never really knew but one side of the spring is elongated and the other side is just like the closed loop. The spring is 5.5in Long and it has an outside diameter I believe 3/8 of an inch but in any case, it's fairly easy to find a spring that's 5 and 1/2 in Long it's more difficult to find one which is 5 and 1/4 in long which is what I figure I need so I decided that they two makes springs 5 and 1/4 in long except both ends are elongated I don't think that's a big deal the only thing you have to worry about is making sure the elongated side does not slip off of the linkage rod which would not be hard to figure out. That linkage rod itself should actually have an adjustment setup built into it so it's a metal rod going into some sort of adjustment setup and then from there it goes out to metal rod again so in the middle some place you can adjust it to loosen it or tighten it that's the way that linkage rod should be built.
