I just bought a 66 F-250 and need to get some information on it.
Data tag is as follows
F25YR888377
125 FM F253 B81 G 25
0600 172 4000 71

The truck is mostly original and in good condition. A 390 4 barrel and C-6 replaced the original motor and transmission. It has power brakes, three fuel tanks and dealer installed A/C. The paint is original blue/white. Headliner is mostly gone. The blue floor mat is still there but has a crack in it. The seat has been poorly repadded and upholstered. dash pad is cracked. The instrument cluster has the extra gauges and engine turned insert. All that is left of the door panels are the sections behind the armrests and door handles. These pieces are white plastic but have an engine turned film overlay that matches the instrument cluster. It also has a white zippered storage box in the passenger door, emergency flashers, radio, cigarette lighter and a storage box in the passenger bedside.
Except for the driveline I plan to keep the truck stock. I have already replaced the armrests with a perfect pair of originals, replaced the outside mirrors and added a clamp on bed cover. My next project is the interior. I own an auto upholstery shop so the seat and headliner are no problem. I have seen some of the reproduction door panels and they don't match mine, I would like to see a photo of some originals. Also when ordering the floormat I was told there is a difference in floor pans , high or low trans hump? How do I identify mine? Thanks for the help.

It's unusual to see an F250 with an A/T and this 'stump puller' 4.56-1 rear axle ratio. Most of these trucks came with ratios of 3.73-1 or 4.10-1.

 

Thanks for the info. The truck had a slide in camper unit in it most of it's life and didn't see much use. I have only driven it once on the highway, I am going to change the gears.

 

I have made some progress on the truck. I located an excellent rear glass to replace the one that has an etching in it. Also I found three real nice original dashpads in Maine salvage yard, mine is totaling gone. I was also able to get some original headliner pieces, they are in excellent shape but I am just going to use them as a template for new ones. Still looking for an original 66 door panel in any condition or a good photo of an original.
