Grant,

The serial number on the cab would ID what chassis it originally had and if the truck has series numbers on the hood that will ID them as well.

3000 Series are 1/2, 3/4 & 1 ton.

4000 Series are 1-1/2 ton.

5000 & 6000 Series are 2 ton.

Then starting in 1956 Chevrolet introduced the 2-1/2 to line up with the 7000 & 9000 Series LCF's and the 8000 & 10000 Series Conventionals.

Hope this helps...and Welcome to the Stovebolt wave
