Is there an aluminum tag on it anywhere? Throw up a pic of that, and yourll get all the details. I'm thinking 37, 38.
Just the two tags on the corner of the firewall in the pick but they are so faded you can't read them.
I'm thinking it's a 37. Will doors from 36, 37, 38 work or are they differient. I know the tall cabs are different. This is a low cab.
looks like a 37, the doors from 36 low cab to 38 should all be the same, 36 cabs still had wood in the A pillar
The 36 has wood in the hinge pillers. and the bottom of the cowl has a raised bump that extends from the door to the hood. 37 has no wood and the cowl bump is angled at the front to clear the fender. gas tank is filled directly into the tank under the passenger seat. 38 is like the 37, with the exception being the cab has a hole in it for the gas filler neck just behind the passenger door. the serial number is stamped into the cowl tag. 36 starts with one of these alpha prefix depending on tonnage and wheelbase. FB, RA, RB, RD, or RC. 37 will have GC, SA, SB, SC, or SD. 38 will have HC, HD, TA, TB, TC, or TD
The rounded top on fenders is 37 or 38 only. The 36 fenders are flatter, especially where they meet the running board. In this pic you can see the body line at the bottom of the door on the cowling from door to hood.
I built a couple 37 trucks and panels and had others for parts. The mid year 36 low cab, 37 and 38 Chevy and GMC all used the same cab so the doors would be interchangeable. Pickup truck only fenders for these years would also be interchangeable. Larger 1 1/2 ton truck fenders are different. Hoods, grille shells and headlights will be different. What is left of your grille shell does look like this may be a 37. Should make a nice build. Have fun with it.
