1936 ford coupes- door glass size

[onedon]

I'm pretty new to the fords so I may ask some foolish questions from time to time. I've had an old 36 I bought some time ago, needs complete resto but mostly complete-has engine tranny int,.My question is I recently bought another, driver, and it was missing the thin trim that goes top and sides of the window for trim cover. I was surprised there is an inch difference between the 2- coupes, in length. Will I find more differences as I go? Could one be a std. and one deluxe?. Thanks Don
