1960 F100 Custom Cab Rebuild Project Questions

[zacstang77]

Im having trouble figuring out what all the serial number means. Its F10C0K24873 which means its an F100 but it has 4WD so shouldnt it be F11 for the start instead of F10?
I got the codes from here: http://1957-60fords.forumotion.com/t63-vin-decoder

Anyways heres the rest of the photos i have from it.. forgot to take before pictures of the engine.. got too excited and just started tearing it apart :P This is my first rebuild project.

When i got to the pistons.. every single cell was filled with antifreeze :/ it think im going to have to take out the engine anyways to check the timing and clean everything.. also have to figure out why the clutch is locked up. Probly wont work on it today with the 40 mph winds blowing.. will update once i continue working on it.
