Raising the door so that beltline on the door is inline with the beltline on the cab will lessen the gaps. This is due to the fact that the doors are slightly tapered in shape. At the door handle level, the door is narrower than at the bottom of the door.
It looks like a fresh rebuild. Do you know if the hinges were rebuilt? All of them need it. The originals never got oiled for 60+ years.
New hinge pins will make door alignment not easier, but rather, possible.
