Anybody: I took this apart years ago and just can't get it back together. Pretty sure the gl*** goes in first, then wing but not finding the right combo.
Probably not much help, but to re-window my '35, I had to drop the whole windup mechanism in first to the bottom of the door. Then came the window and sort of ***embled gl*** to mechanism inside the door. In your case, then add the wing if its the front channel. Just guessing here.
