I purchased the factory assembly manual for the Chevy AD trucks, there are charts in it that give what the "factory" dimensions should be. I have the cab mounted right now on a piece of a AD 1/2 ton frame from a junk truck. Figured this was the best way to help maintain squareness ect.....
The cab I have has been damaged on the passenger side and was repaired years ago. I know the original hood, someone had cut the curve to match the cowl. They had cut the cowl right up along curve for the hood opening and the louvered vent on the side, then overlapped them a bit and brazed it back together.
From what I can tell measuring it looks like this side of the cab has been "pushed" back some. They repalced the rear cab corner but they cut the lip off the door opening where it wrapped around for the cab corner to mount to.
I would say, needs new rocker, inner and outer cowl panels, inner to outer cowl panel, cab corner, floor mount and floor panel ahead of the seat and part of the toe panel.
Driver's side is better off measurement wise, but needs pretty much the same panels replaced....
Good cabs in the north east aren't easy to find anymore.
