jim911,
The 1946 cab is distinctly different from
the 1951 cab. Which style cab do you have?
8PK110526
could be a 1946 Vehicle Serial Number.
It could be a VSN plate from another truck (taken/used for titling/registration purposes).
8 = Atlanta, GA assembly plant
PK = 1946 4400 truck
I = August
110526 = 110526 - 1000 = 109526th truck out of that plant that model year
You say it is a 46 chassis and 52 doors?
How did you ID the chassis?
Where did you find a chassis ID?
What is the code on the motor (pressed into the block just in the ledge to the rear of where the distributor goes into the block). Motors are often replaced.
