[updated:LAST EDITED ON 19-May-02 AT 05:51 PM (EST)]Here, by request! (As a picker, I learned REAL FAST to stay within my repetoire, but THIS I've got the books for!)

These are the Trim codes from Vol I of the 1966 Ford Truck Shop manual. I'm still researching the trim codes for 61-65 from the Dealer's Ford Truck Parts Book to confirm these are the same for 64 and 65. Most other interior body trim parts are the same for those years, so I strongly suspect they are, BUT I haven't nailed it down in black and white. Those codes are in the Soft Trim Section, and I haven't found that - yet.
Here goes:
1 - Grey Vinyl
2 - Blue Vinyl
3 - Green Vinyl
4 - Beige Vinyl
5 - Red Vinyl
6 - Black Vinyl
A - Grey Woven Plastic and Vinyl
B - Blue Woven Plastic and Blue Vinyl w/ Foam Cushion
C - Green Woven Plastic and Green Vinyl w/ Foam Cushion
D - Beige Woven Plastic and Beige Vinyl w/ Foam Cushion
E - Red Woven Plastic and Red Vinyl w/ Foam Cushion
(No F - I)
J - Grey Vinyl w/Foam Cushion
K - Blue Woven Plastic and Blue Vinyl w/ Foam Cushion
L - Green Woven Plastic and Green Vinyl w/ Foam Cushion
M - Beige Woven Plastic and Beige Vinyl w/ Foam Cushion
N - Red Woven Plastic and Red Vinyl w/ Foam Cushion
O - Black Vinyl w/ Foam Cushion

81 - Conventional Cab
84 - Cowl and Chassis (no windshield)
85 - Cowl and Chassis w/Windshield
91 - Tilt Cab

I don't know the difference between A - E and K - N. Anyone?

 

I don't know the answer, but I'll make a guess: either the Ranger or crew cab used a different code. (?)

Some, but NOT all the Ranger packages had a DSO code in the DSO location on the vin tag
