Customs 35-36 ford measurement needed

Hello

Could anyone tell me the length of a 3 window roof opening from front to back down the center?

Also the length from the top of the rear window to the back of the roof opening? Or if that is the same as a 5 window?

Thank you
Jim

 

Here's what I came up with,

3 window Roof opening at center: 20" inside to inside flange

Back of roof opening to rear window: 15-1/5"
(edge of flange to window opening measured on out side)


Don't think these dimensions are same as 5 window

 

Thank you very much!!!!
