The passenger side door latch on my 58 works fine most of the time, but occasionally, the door won’t open. When pulling on the inside handle or pushing the outside button, it doesn’t feel like anything is sticking or binding, but the latch just won’t release. If I push hard on the door, trying to close it further, it doesn’t seem to move any, but it frees something, because the latch will then work fine. All the parts look good, and I’ve adjusted everything in every conceivable direction, and it makes no difference.
