As shown below, Ford said that for a regular-production vehicle there would be a two-digit code indicating which district sales office ordered it. Now, let's talk about what that space on the certification label was actually used for.

(See in General Information in the 1981 Light Truck Facts Organizer and of the 1994 edition of the MPC.)Įssentially there are 7 Ford publications - the yearly factory shop manuals - that say DSO is District Sales Office, and 8 publications that say it is Domestic Special Order - the yearly light truck organizers plus the one master parts catalog.Īnd these two uses of the term DSO continued well into the 90's, as shown by the pictures from the 1994 Taurus and 1995 Continental factory shop manuals. Domestic Special Order: The dealer facts books, aka Light Truck Facts Organizers, as well as the 1980 - 89 master parts catalog define DSO as being Domestic Special Order.And, you'll see it in the next picture, which is from a 1986 FSM. You'll see that on the first picture in the gallery at the bottom of this page, and that's from page 10-00-16 in 1981. District Sales Office: The factory shop manuals for the Bullnose era show DSO as being "district sales office".And while I'm no expert, I do believe the best source on the subject is Ford's publications.

There are many opinions about what "DSO" means on a Ford vehicle's certification label.
