1964 Dodge Dart 270 Slant Six Restoration

My driver’s side door is out of alignment and has to be lifted up to close. I looked in the FSM and it seems i can adjust it, but larger issue here’s is that water is leaking in from the front of the driver’s door into my interior.

Hopefully alignment will fix that? My floor pans are already rusty and I’m looking to replace them, but this issue doesn’t help any until I can do that
