400 series 2 1/2 ton is a Rare truck. You don't run across them as much as you do the 450, or 470 series trucks, which are rare in themselves. Great find. Rob English (
www.oldgmctrucks.com) has one. Check the back of the glove box lid for all the trucks vitals. It's not a 4 1/2 ton. My '52 470 series GMC COE is a 3 1/2 ton.
