Real 4x4?

I saw this truck on “Bring a Trailer”. Claimed to be an original 4WD https://bringatrailer.com/listing/1966-ford-f-100-7/ and it may well be. But I commented on the front wheel opening not looking right for a factory 4WD. I tried to run the VIN on FTE, came up invalid, as it was looking for more digits. F11YK86219
Possibly I misunderstood when @NumberDummy mentioned about the wheel opening being wider for a 4WD, or maybe they only applies to 3/4 ton and up.
Anyways, where is the VIN decoder for the older trucks?

The F11 in the VIN indicates it is a factory F100 4x4. The F100 4x4 trucks didn't always get the wider opening fenders. Neither did the F250 4x4 trucks in all years. This gives the idea. But in a nutshell it is correct for front fenders in this case since it is a '66 model year.

The wide opening fender was used on all F 350's '61-'66 regardless of wheel size. Other applications of this large opening fender are model and year specific. 1961 to 1964 F 250 4x4's got the narrow opening fender when equipped with 16" wheels. 17", 17.5", and 19.5" wheels got the wide opening fenders. Ford changed the rules in 1965. All '65 F100 4x4 and F 250 4x4's got the wide opening fender on all wheel sizes. In 1966, the F 250 4x4 continued with these rules, but the '66 F 100 4x4 used only the narrow opening fender on all wheel sizes ( 15", 16", and 17.5").

I'm working on an automated VIN decoder for our trucks. It will be a bit more thorough than some in the past since it will account for the larger trucks as well with the Detroit, Caterpillar and Cummins diesel engines, etc.

Here's a snippet of the SQL code

Yes, the F11 indication for 4WD is the same information supplied by another reader. He said it had a lot to do with wheel size on the truck. Thanks for clarification, and thanks for working on the decoder as well!
