1994-2002 Ram Question

Hi everyone! Been awhile since posting but still lurk around but don't sign in. Lol.
Anyways. I've been gathering body parts for that 1996 2500 I bought to replace hail damaged parts and was able to score some good straight parts today. One of the parts is the passenger side door.

My question is: Are the doors different between a standard cab and an extended cab in those years? The overall dimensions of the door seems to be the same but the pillar at the back of the door is about 1/2" wider than mine.
I guess the real question is, will a door from a 2000 Ram 3500 ext cab fit on my 1996 Ram 2500 stand cab? I though they were the same from 94-02.

Thanks everyone!

Oh, just checked rockauto and it shows the same part number so not sure why the door is slightly different.
