HOW TO DECODE YOUR 1965-1966 VIN / WARRANTY TAG
The following tutorial pertains all US-built 1965-1966 Ford F100, F250 and F350 trucks. 
 


 

From the factory, the warranty tag was located on the outer face of the driver's door. The information on the warranty tag includes the V.I.N. number, the wheelbase in inches, color, model type, body type, transmission type, rear axle, maximum gross vehicle weight in pounds, certified net horsepower and domestic special order (DSO) numbers (if applicable).

NOTE: The V.I.N. can also be found stamped in two places on the right-side frame rail. Scroll to the bottom of this page for more info.
Be sure to check to ensure the V.I.N. stamped on the warranty tag matches the numbers on the frame

FIRST ROW - THE V.I.N. (SERIAL NUMBER)

The first 3 digits of the V.I.N. (serial number) indicate the truck series:

NOTE : The consecutive numbers for trucks were assigned just like Ford cars in the period, IE each assembly plant started with the same sequential number. Thus, the first truck in Kansas City production in 1967 would be assigned 580,001, as the first truck assigned to San Jose would also be 580,001. The unique serial number identifier would be the plant code (the letter preceding the six-digit consecutive unit number).

 

SECOND ROW


The W.B. (wheelbase) code indicates the wheelbase in inches:
- 115" is a short wheelbase (SWB) truck - F100
- 129" is a long wheelbase (LWB) truck - F100/F250
- 132" and 152" is an F350
- 147" is an F250 crewcab (1966)

The BODY code - The first one or two digits identifies the interior trim and the last two digits indicates the type of cab. Use the body type code in conjunction with the model code to determine the exact body type of the unit.

NOTE:  '81' is a conventional cab. The 'A' and 'B' suffix shown below only appears in the MPC for parts ordering purposes, but the suffix does not actually appear on the warranty tag.  
"Conventional cab" refers to the F-series in general, as opposed to the C-series (tilt cab series), T-series (tandom axle series), B-series (school bus series) or P-series (parcel delivery series.>

The D.S.O. code:

Identifies the district which ordered the vehicle. If the vehicle is specifically built on a D.S.O (Domestic Special Order), F.S.O. (Foreign Special Order) or L.S.O. (Limited Production Option), the complete order (invoice) number will also be reflected under the DSO space including the District Code Number. If the truck is a regular production unit, only the District Code will appear.

TRANS NOTE 1:

To everyone who uses the factory's '65-'72 Master Parts Catalog (MPC) Final Edition 1975 as a source for decoding warranty/data plates: there is a very misleading typographical error in the 'tutorial' at the beginning of the MPC (General Information - page 75) where it lists the transmission codes for light-duty trucks.

Code A has decoded to a L/D or M/D Ford 3spd from '61 thru '65. Then in '66, the code for the L/D and M/D 3spd changed to Code C and the NP435 became Code A. This is shown in other areas of the '65-'72 MPC....everywhere EXCEPT the 'tutorial' at the beginning of the MPC (General Information - page 75) where it gives you the transmission codes.  A simple typo there creates the impression that Code A is correct for BOTH the 3-spd AND the NP435...which obviously is impossible.

In Fig. 01 at right, this is from the 'tutorial' at the beginning of the MPC, you can see the blue arrow pointing to Code A for the 3-spd. Right below that in the green arrow, you can see the listing for NP435, where it states 64/ (which means 1964 and newer). The red arrow for Code C shows the REAL 3-spd listing.

Where the green arrow is pointing to the date for Code A, that SHOULD read 66/, NOT '64/! Then you would actually read this as Code A being for the 3spd up through '65 and then Code A became the NP435 in '66.

See in the description here it tells the viewer to go to Section 70 for more info? (Section 70 is the section for manual transmissions, A70 is for automatics.) When you go to Section 70 and scroll down to the listings for manual 3spds for 1966 (Section 70, page 19, shown in Fig. 02), you can see that they DO have things correct here. This image shows the Code C 3spds.


Now, when you proceed to the section for '66 4-spd applications (FIG. 03), you can see that Code A is indeed for the NP435.

So it's the quick tutorial at the front of the MPC's General Information section that is incorrect in the dates used for Code A. The other listings in the MPC show Code A correctly. The dates (FIG 04 circled in red) SHOULD read '66/ instead of '64/.

LOCATING YOUR V.I.N. STAMPINGS ON THE FRAME
In addition to the V.I.N. on the driver's door data plate, the number is also stamped on the frame in two different places, both on the topside of the right frame rail. The first one is in the engine compartment, just below the alternator on two-wheel-drive pickups or just behind the front axle on four-wheel-drive pickups.

The second number is stamped just under where the seat would be located. You'll likely need a flashlight and small mirror to read this one.

These frame stamps are usually hard to read, so be sure to grab a wire brush and some rags to clean the grime off. (NOTE: the picture at right is a '67 frame, but the stampings should be located in the same locations. There have also be isolated reports of a VIN found stamped in non-typical locations, such as on the left-side frame rail under the seat area.)
