It is so unusual to find an unmolested mid 30s truck! When this all original 21,000 mile 1937 GMC appeared at a recent New England truck show, we had to take notice having never seen the correct installation of the small 3/8′ bead cab windlace on an early model. Our camera did some recording.

Rumors from a few past customers were correct, the attaching position at the upper front door corner changes. Take note of the way the two pointed windlace ends meet when the door is closed. On the top and back side of the door opening the windlace is attached to the cab. At the front, the vertical piece is secured to the door edge
Note the gap between the two pointed ends of the welt. Some shrinkage after 70 years.
