Chris, if your windows are from a 52 the doors will have push button handles that came out in that year.
I know what your going through. When I got my panel it had a 1950 door on one side and 52 on the other. One with wind vent one without.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
