Door latch problems on a 1972 Ford Custom 500
I have a new door I'm putting on the driver side of my car because the one on there has a huge dent in it from getting backed into, and the latch on the replacement door doesn't work on the inside or outside. In short it wouldn't open the door so I was wondering if it would be worth it to try to fix the latch and inner workings or just take the working one out of the door i'm replacing.
