Done.
Elongated hole in regulator bracket.
Fitted bushing/ insulator installed on the outboard side of the bracket.
Corresponding bushing/insulator and washer/spacer on the inboard side of the bracket.
Used a dab of epoxy to hold it into place since the original crimp was defective allowing the plastic insulator to move. Probably the cause of the original failure. The nut was temporarily installed until the epoxy set.
Voila`! Back in place, freshly lubed, ready for moisture barrier and door panel.
Cost? Some head scratching, 20 minutes of re-fitting the bushing, a hour's wait for the epoxy to set and maybe a nickel's worth of epoxy.
Sure beat the $80+ for a new regulator AND I didn't have to fuss about with swapping the motor, the slide jaws, front window guide and re-alignment.
