you might have to do some adjustments to the window frame itself. I am not sure how much of the glass actually sets in the frame. i will be taking measurements this weekend to see where i need to make my weld points.
Please take pictures of the glass and the window so we can atleast get a visual of the problem you are having and the one i might encounter.
thats the beauty of these old trucks. you have to massage and persuade them to fit your dream specifications.
