Help! Wiper pivot stud broken

You can remove the stud by pounding it out from the back side. Grind a small amount off on the back side then hammer out with a punch.

I recently removed all the studs out of both wiper pivots and the motor to where it connects the linkage. I drilled them out and tapped them, and replaced them all with bolts I JBwelded in place. Then I'm using nylon bushings, washers, and nylocks to hold in place, instead of the crappy plastic bushings. I'll try and take pics tomorrow for you. I'd recommend doing it right and be done with it.
