The passenger side window won't roll down on my '67 1/2 ton. I've gotten as far as removing all the screws in the panel and the arm rest, but I can't find the pin or screw on the shafts of the handles. I have an idea as to what it might be, but I can't find a way to pull them out. It doesn't help that there's a layer of hard-to-clean-off dirt over the shafts either.
