It's a '46 1-ton with a 228 and a 134-1/2 inch wheel base.
So many of the years that start with a pair of letters require a production number to determine the year that my tool requires the full serial number to be able to be sure what its looking at. E is actually the only letter that when used as the first character means only one specific year. I've no idea why GMC did things the screwy way they did.
EC252001 thru EC2522701 were all made in '46. Put in the whole number and my tool should get the year right but the wheelbase wrong.
These six-lug wheels, are they similar to what is on the later 1/2-ton trucks, or more like what are on the larger trucks?
A '46 Chevy 1-ton appears (from the resto pack) to have an Eaton HO72 with 5.13 gears and 8-lug hubs. A '42 Chevy 1-ton appears to be a different rear with 4.55 gears and 10-lug hubs on the back.
I don't have an easy source for details like these on a GMC.
