I had seen an ad for an engine that included the X15 info but lost track of it and didn't know what they meant at the time. According to the info shown further up in this thread, they put the 6 cylinder engines in the 1928 2 ton trucks, so it must be a 1926-1927 OC. The Dodge Brothers cars had the new 'C' 5 main engines in them in 1927. I'm wondering it that applied to the trucks as well? I've looked closely at the area of all four front spring hangers as well as the rear step brackets as shown on the Graham brothers info. No number is visible. at any location. Since I'm not planning on titling or registering the truck, it isn't a big deal. I'm happy to know what it is within a 2 year period.
Does anyone know who manufactured the wheel rims? I'd like to know what to ask for when I start looking for some.
