Relative resistance of the wiper linkage

The only difference you'll find other than left and right hand is how the linkage attaches. Some use retaining clips on the pins and some use nylon ball sockets. I can't imagine how you broke it but I know chit happens. Pot metal does break easily.
I just assume worse things happen to better people and carry on. LOL
Let me know how you'll proceed. If we need to take parts from one to repair another, we can :)
