David, I see you posted while I was typing. The VIN checks out perfectly as a Chevy 1/2 ton, 127" wb IE:

4C154H164906

4=1964
C=Conventional Cab
1=1/2 ton
5=127" wb
4=pickup
H=Fremont, Cal.
164906=64906th production (#'s start at 100,001 each year at each plant)

The VIN does not indicate the style of bed as stepside or fleetside. Don't confuse VIN # with model #, they don't correlate.

The 1964 brochure shows the four C10 Model's as:
Model C1404 is the 1/2 ton short bed, stepside.
Model C1434 is the 1/2 ton short bed, fleetside.
Model C1504 is the 1/2 ton long bed, stepside.
Model C1534 is the 1/2 ton long bed, fleetside.
