1940 Fords and cigarettes

And the ventilator feature makes the fine-tuning adjustment of the window regulator a big PITA. Everything has to be just right for the regulator to transition from up-down to back-forth movements.

very true. glass placement in the track is critical to this function. i replaced the glass in my rear 39 tudor and had it working fine. proceeded to crack new glass installing window garnish. back to glass shop. with new glass installed could not get window to go up all the way was trying to move foward before it should. i finally had to alter the mech. to make it work. had that piece in and out a dozen times and it was a real pita.

Yes. Bottom glass channel must be located on the glass in exact factory location.

Ventilation was the main purpose, in 1940, as the air conditioning usually only worked from late fall to early spring. Except those lucky few who could afford a 1940 Packard!
