Since I am not there, it is hard to see exactly what you are seeing. But, I have to say, after installing the new door seals, in my 53 3100, they are considerably harder to get to shut. If your old ones were worn out, you probably got used to the way they shut. It is quite a difference between brand new ones and old ones. They do seem to get easier as the seals get pressed together, from the door being shut. Also, if the windows are up, it more difficult. I know that these trucks are far from air tight. But, letting the air escape out the windows, when you shut the doors, helps quite a bit. At least, it does with mine. Perhaps there are some more adjustments on a 56, than on a 53. If you want the door to fit flush with the cab, you just gotta, get aggressive shutting the doors for a while. Hope this helps. Maybe somebody will chime in, that has a 55-57. They very well may have a better answer for you.
Good luck.

Rugo Just installed new seals and to get the doors to latch requires pushing/slamming. Slammed it so hard, the door lever and window winder fell off onto the floor (should have tightened the set screws  ). This is from the out side. Closing from the inside won't be easy. Question: how long did you have to wait until the seals conform to the body and things get easier?

Adjust the door striker outboard of the current position so that it will close without slamming, yet still compresses the seal somewhat. The door edge will be slightly proud of the door opening at the rear. That's OK for now.
Over time, the rubber will lay down and behave, then you can move the striker inboard and the door will close without slamming, and be flush with the door opening.
This has worked for me every time.
