My 49 1/2 ton has all of the evidence to make it a "late" 49, "Chevrolet" and "3100" badges on the hood, door weatherstrip in a metal track and a build date of August 49. Now I find out the hard way (the late version I bought doesn't fit) that the headliner is the "early" 49 style with screw in center channel. Has anyone run across something like this before?
