Earl Shibe will paint any car, any color, for $99.95 (thats the roll down the windows and spray package, I believe)
If that's too rich for your blood, WalMart sells spray paint for 89 cents a can!
From what I understand, the old big bolts were not painted all that well in the first place, so a quickie paint job would help lend an air of authenticity to the vehicle and pacify the staunch purists at the next show!
My '46 2 ton has 10 lugs rear (dualies) and 5 in front with giant fenders, it's my understanding that they didn't rig them like that till you got to the 1.5 ton trucks.
I've heard that some areas didn't have a 1.5 or 2 ton rating for a non-commercial vehicle, so it's possible to find a vehicle registered as a lower "tonnage" than it says on the title.
My '46s title says 2 ton, it's VIN suggests 2 ton, but the last time it was registered (for non commercial, private use), it said 1.5 ton.
The 235 might be another indicator if the actual "tonnage" of the truck.. i've heard that the 235 wasn't common in the trucks till they hit the 1.5 ton mark.
See if you can get the number stamped on the Mfg plate (located under the hood on the passenger side twards the windsheild) then plug the numbers into the VIN Cruncher (
