The tab on the spring goes through the slot in the pivot. Both of mine broke off and fell to the bottom of the door. I heard one of them break and fall. I think they are swaged in place. The spring tab rotates about 90 deg and stops at the mounting boss near the top of the picture. With less tension on the helper spring your windows will go up more slowly. Live with slow windows, rig up a replacement pivot pin or replace the whole regulator ($$$).
