As you all know, a common point of failure in these cars is the door striker. Decades of use and poor engineering eventually leads to the strike mount fracturing itself from the door. Most repair methods are crude but functional. In this case someone had booger welded and threaded a flat washer as the repair. Time to fix it the "right" way with a commercially available repair kit. Received the kit and the instructions were good, but the keeper was installed upside-down. Had to grind it off and flip it. Otherwise everything turned out great.
One day I'll paint it, but for now consider it repaired.
