First Post looking for help

[slategrove]

I just purchased what was advertised as a 1967 C-10 with I6.

After looking through the site here, I found that the VIN didn't have the right amount of letters/character...it has a Kentucky issued VIN plate in the door jam, held on with a single screw (which I'm questioning the legality of).

I looked inside the glove box door and found a vin of CE148Fserial# which I decipher as a 1948 pickup with a V-8 gasoline powered engine (if the glove box is original)

Below the VIN in the glove box is a list of option codes and the explanations for those codes, but on none of the 5 codes/ecplanations are all lines legible...I'm wondering if anyone knows what the codes mean?

450???-Dark Blue (I get this one)
4V37EA- (illegible explanation)
4604JA- (illegible explanation)
4U63HA- (illegible explanation)
4G60AB- (illegible explanation)

Engine casting numbers: 3921968 (passenger side middle of block)

Any help on the codes & engine casting #'s would be greatly appreciated, and advise/ideas on the VIN ?

Thanks in advance,
