  1. I'm needin some info in this 55-57 GMC COE
    I just don't know enough about these oddities...
    So any help would be great...
    Ton-age maybe...This ole boy is a beast!, says 12,500# on the door.
    It says "370" on the this CI or a series #?
    It is a 6 cyl engine..also it has hinged front fenders for engine access (kinda cool/different) never seen this before...
    Here's a few pics...Thanks~[​IMG]

    The sources suggested are the same ones I would have pointed you at.

    That truck isn't usually called a COE, but instead a LCF for Low Cab Forward. I can't explain the name, but that is what they were called.

    The 12,500 on the door is probably the licensed gross weight. What weight does the serial number plate show? That would give a better idea the actual size of the truck.

    370 is the model, and I think a 370 is a 2-ton or a 2-1/2 ton, but I don't know these models well enough to be sure.
