69 Dart door jam question

I've owed my Dart for almost 20 years. Worked on it off and on and this looks like the year for the Dart. A friend was over looking at it because he is going to do the bodywork on it. He noticed the door latch jam stud had welds around it that doesn't look factory. Both sides are the same. Is this common or did someone try to beef it up for drag racing?

Very common rust spot. Yes, it looks someone did their best to repair it or beef it up.

These guys have the fix you need. Very easy to install, and comes with step by step instructions. FYI, there is a separate Drivers & Passenger part number.
