The Stovebolt Site Forums The Parking Lot Big Bolts COE ID# confusion

I recently bought a GMC COE that is listed on the title as a 49 and after getting it home I was told by another that it was a 39 based on the model # and serial #.
Model # AF 602 SN 515.
HP 92.5 @ 2600 RPM
Max wt 23000 lbs.
I only bought the cab which was heavily modified so i don't have any other numbers to fall back on.
I just joined the forum and tried to find other forum posts that discused this.
Does any one have a suggestion? Thank you for your help.

In the Heavy Duty Line of GMC COE's the body style stayed the same from 1939 until 1949. The only difference is the '46-'49 models have a alligator type hood that splits the grille in half. The earlier version has a one piece grille with two access panels.

Spanky,

For the sake of those in the 1.5-2 ton Chevrolet big-bolt world, what size trucks are you referring to as the Heavy Duty Line of GMC?

Heavy Duty line in GMC Trucks was considered "500" series, & up. The "400" series trucks were considerd Heavy Medium Duty, & "300" series Medium Duty. Truck in question here is a 600 series COE. Chevrolet didn't have a Heavy Duty Line until the 1956 model "7000", & "9000" series Low Cab Forwards(LCF's), & 8000, & 10000 series conventionals came out.

You are assuming too much, Spanky,

Tell us the "tonnage ratings" for those series.

For example, my 350 series COE is heavy Medium Duty or Medium Duty and is a 2-ton truck?

Thanks,

Thank you very much. My truck has the alligator hood with split grill and no side assess panels. I am happy to have the confusion cleared. My next problem is how to convince California DMV that it is not a commercial truck and the 1-ton P-30 chassis it is sitting on is "Really" what should count in figuring the capacity and therefore the registration and tax.

Are there any California truckers that have experience licensing vintage HD trucks? I will be using this for more than just parades. I will be using it as a (sorry to say) car hauler for a vintage sports race car.

300 series = 1 1/2 ton, 350 series = 2 ton, 400 series = 2 1/2 ton, 450 series = 3 ton, 470 series = 3 1/2 ton, 520 series = 4 ton ton, 550 series = 4 1/2 ton, 600 series = 5 ton.
