Ford service manuals

[FoxChassis]

Who here has Ford service manuals for 1987 through 1993?

What I'm looking for is the list of DSOs in the front of the books.

A question came up in one of the facebook groups about DSO 56 buck tags from a 1993 unit. In the tech section here DSO 56 is listed as Davenport (IA) but I don't think that is correct. What I think happened is DSO 76 (Denver) was replaced by DSO 56 between the 1991 and 1992 model years. We have seen this before with DSO 17 being replaced by DSO 27 around the same time frame.

From the VIN Project:
DSO 76 = 1983-91 (Colorado, Idaho, Nevada, New Mexico, Utah, Wyoming)
DSO 56 = 1992 (Utah)
