Post by: Rapid Roy on November 07, 2021, 12:03:41 PM

Is the rear cab wall below window a double wall? If so, does anyone know how thick it is?

You have about 18 gauge metal then about 1.5" then the inside cab wall. So the is empty space between outside metal skin (single) and the inside cab skin (single). You can go to my build thread if you want and see. I cut our the rest window metal an welded in new metal due to rust.http://forum.73-87chevytrucks.com/smforum/index.php?topic=38009.15

Hope this helped you out. The same all around the window except for a few brackets inside for seat belts etc.
