My teacher always told me that if one person didn't know the answer it wasn't a dumb question, so here goes.
Are cabs on the '47-55's two piece?
On the inside of the cab there appears to be a flange holding the roof to the lower portion. On the outside the roof section appears to indeed have an unfilled seam where the two meet. However at the windshield post it all appears to be one.
That Ebay truck with the tree damaged roof is starting to look better if they are two piece.
Thanks for any knowledge on this that you can share.
