Hello CFS, I am fairly intimate with those styles of cabs as I have just finished one. [36 Ford on Ranger] You don't have a '37 Ford, that is a '36. The '37 has a two piece windshield and two equal sized guauge holes in the driver side dash, although we can't see that in your picture. '35's and '36's have one piece windshields and three holes in the dash, a big centre one and two smaller ones. The '35's have a squarer front bottom corner at the A-pillar to cowl merging. That is a '36 cab. The '36 grille is the nicest one, ever. The '35 is almost as good and the '37 is yuccy, but not as yuccy as a '38.
The first pic and the finished dash are '36s and the second red one is a '37. The grille is a '36.
COOL PRIZE.
