Slick69,
Where did you find the "vin #"? On a title, registration, or the egnine?
Can you post a link to a photo of the code?
Might the prefix letters be HBA? If it is the engine serial number (pressed into the block to the rear of the distributor),
it looks a little like a 1950 truck engine serial number. If your engine is clean and accessible,
find and post the various casting codes, date codes, and engine serial number.
A 1950 model truck night have been built in 1949, sold in 1949, and first titled/registered in 1949. Stranger things have been reported.
Do you have a Vehicle Serial Number tag between the hinges on the driver's side?
