I started to rebuild my doors for my 59 3800, i put the new window glass in the old frames awhile ago i went to put the glass in the door and set it into the window regulator, i saw that the rubber that seals the bottom of the glass in the frame has a lip that swings up and out , i put it going to the back side of the glass (facing the cab), i can't remember if it goes that way or facing the outside of the glass (facing out) i think i did it backwards, can anybody set me straight, im not really sure what these parts are called so bear with me thanks
