I have two different sizes of springs. One is seven coils long and one is four coils long. Should they both be seven coils long ? If so, what is the smaller one for ? Thank you very much. 71Z

sounds like the shorter one may have broken

Look at the cam on the door hinge to determine if the hinge is one stop open or two stops open.  The lower hinges changed around July 1972 from one stop to two stops; the difference between the E4100 series and E8200 series of part #'s 80420 and 80421.
