I tried a couple of Dorman bushings for the smaller one. They seem tight, had to use the vice to get them in, the whole bushing rotates when I move them manually.
I was going to put it in to test them and see if I should keep on looking (no change to the larger ones) and the dang pivot (name?) for the wiper arms stripped! They were close already but I thought I could get away with this.
Has anyone solved this problem? Has anyone tried running a smaller size die over it and using a smaller flat nut?
