34 Ford 3W help

My 3W body is rough. It was a roundy round car at one time. I would like to check the measurement across the body at the door center hinges. Can someone measure their body, outside to outside at the belt line. If I have that number I can square the body.
Thanks

 

Bump for Xman!

 

Outer to Outer Beltline 55 13/16

 

I'm at 56 3/4 so I'm not to far out. Thanks for taking the time to measure it for me.
