Hi jason93, and welcome to Stovebolt!
Like Rusty Rod said, 1937 was a transition year. I understand that there were two styles offered during the year - the older "high cab" and the newer "low cab". But all that means nothing if your machine is a Frankenstein like my '37 is ;'}
The guy I bought mine from had built several '37's and, when he finally lost interest, sold off the remaining parts & pieces to me, along with a "conglomerate cab" built with close enough parts.
To further complicate matters, while going through a divorce my X had my truck hauled off as an abandoned vehicle! I had to purchase my own truck back from the auction! When I got it back I discovered that she had told the cops that it was a '36 and so they titled it that way.
So I am the proud owner of a 36/37 Chev/GMC/Maple Leaf pickup truck!
This makes it interesting when shopping for parts (as if trying to buy something for a 70 year old truck isn't bad enough!). From what I've been able to determine, the low cab '36 shares the same dimensions as the '37. If you compare pictures from the Stovebolt gallery you will see a difference in the front fenders between the two years. I do now know whether the differences show up in the junction of fender to cab however.
If you are referring to the bolt-in toe-board, you might check out Jim Carter's offerings (
http://www.oldchevytrucks.com/) - they list the same part for years '36-'38 (part number FL 168). Any other sheet metal and you are pretty much on your own ;'{
Good luck with your project - glad to see more '37's out there!
