The Ford VIN in that mid century time frame was just a year or so away from having a change over of the data plates that started in 1951 or 52. The "9" is 1949 and the 8BA is the V8 engine. The 6-cylinder would be different. KC is the assembly plant. The stamping on the top cowl area give the body type, paint code, and interior code. In 1951 or 52, depending on body type and assembly plant, they started consolidating everything on the data plate. Data plate info is usually found in the year specific body or chassis parts manuals.
The 1949 commercial pickups were real confusing. The 1949 year code carried over into 1950 so a person can't tell which year it was made. A fella over on the Ford Truck Forum has a listing of serial numbers to narrow down the year of manufacture.
