If you want to make an accurate one, this is hard.
This is the phase 2 with the centered door latches- as you said.
One way:
Kato C30-7 body cut down.- gives the correct doors, latches, and roof. Trim same as my article said.
Kato U30C radiator section.- give correct radiator section.
Kato U30C fuel tank chopped down.
Atlas U23B walkway WITH anticlimber (essentially, the conrail version if I recall).
The Atlas U23 nose and cab would probably work best too for best cab to walkway fitting.
I thought about making one of these once, but never did.
By the way, has ditch lights on front
and back if you go with a year later than this photo.

Another interesting thing about this one is that they changed the trucks at one point. SO you have two options.
