Hi Jim, I am restoring my first classic truck, a 1951 Ford F-1. I noticed the number on the cab just under the hood is different from the number on the frame. The VIN code on the frame indicates the truck came from Kansas City. The number on the cab is KCB15E 348. I am assuming the KC from the cab number stands for Kansas City. Do I have a marriage of parts or is this cab original to the frame. What you think? Can you help me out?

Thanks so much,

Hello Eileen, Congrats on your new project! Now let's see if I can help you find an answer to your question. The number you gave me from the plate under the hood (KCB15E348) has me scratching my head. Aside from the KC the rest of the characters make no sense. As far as I can tell, the 1951 and 1952 pickup serial number should look something like this: *F1H1KC1XXXX*.

The first two characters designate the truck series (F-1), the next (H) is the engine code, next (1) is the year code, next (KC) is the plant code, and finally the series of numbers (starting with 1) is the production sequence.

Over the years it is very possible that the cab and sheetmetal have been switched from one chassis to another, but as far as any DMV will be concerned, the number stamped on the frame is the true VIN.

Another bit of info I ran across regarding the 1951/1952 F-1 is that some had serial numbers in three different places—under the hood on the right side of the firewall, on a plate attached to the inside of the glovebox door, and on the right side of the front frame crossmember (near the right side engine mount area). I hope some of this helps, and do me a favor, let me know what you find 'cuz you have me curious as heck.
