1965 Dodge Dart Door Locks...

Might be possible although I've been told they are unique to each side with different part numbers. Give it a try and let us know,
I'll take it to the locksmith in the morning and see what he says.
It could have been the younger guy that mentioned it, so I'll be sure and ask "the old man".
Don't want to remove the passenger side door panel if they can't be swapped out.
I'll report back with more details... :salut:
