WW pivot clip

A 74 model might have something different at the linkage to pitman arm only and 2 speed or 3 speed did vary there for some year models. Your other 3 connections to wiper pivots are white plastic sockets for a ball end stud. Most any part store could have them on there HELP line, in a package of 3 if my memory serves. The first/most force transmission is pitman to left pivot so that socket bushing at left pivot is the most common first failure. Replacing all 3 while in under there is the best plan? That explains package of 3? Makes sense to me.
How long the new bushings will last compared to the originals? I wont go into all that here. Just know that these Chrysler products are of the very very few who have serviceable/renewable linkage bushings. Most mfgr's replace pivots, linkage and all for good reason. Good luck with yours.
