My 1954 Suburban Carryall has 4 big bolts holding the rear body to the frame.
On my Suburban, there are no pads or blocks between the frame and the rear body/floor.
My Suburban sits lower in the the rear than in the front.
I am guessing that originally there were wood-blocks and/or pads?
I will check the Factory Assembly Manual (if I can find it), but does anyone know if there were 4 mounting-pads and/or 4 wood-blocks under 1954 Suburbans (and, probably Panel) floors?
Maybe 47-55st Advance-Design rear body-mounts were the same?
