Hot Rods Measurement needed for ‘33 Ford 3-window Coupe

So, trying to help a friend out who doesn’t have computer access. I helped him pull a 33 2-window out of a barn last year. The sub rails are gone, and he has bought new to install. He is looking for a width measurement from back (hinge side) of door jamb to the same spot on the other side of the body, can anyone help out with a measurement please? Thanks in advance!

 

Can you post a few pictures of the project your working on?
