The build sheet could be on the trans tunnel, or it was taken out at the factory(?)

I have not had time to dig this week. I've been between Weirton, West Virginia and Dearborn, Michigan this week for work so the car is getting worked on while I'm away for now. All I can do is gather parts and research the history for the time being. I think I have to remove the front seats and then pull the carpet further so that I can get a better idea of the other items that can tell more of this car's history from the build sheet.

Odd that the DSO on the door tag and buck tag is 76 (Denver), as is the door tag image on the Marti Report, but the dealer code starts with 56.

So the closest available Ford Fleet sales office to Idaho is in Colorado? ISP did not use Fords at all until the late 90's. Typically, Idaho used Chrysler products for many years and in the mid to late 80's started going with Chevrolet. I can only speculate without talking with Ford Fleet that due to the lack of Ford police vehicle sales to Idaho, they would have to order any package or special service vehicles from a sales office that normally specifies them and most likely has available order slots. The part that is strange is why Colorado and not Utah or Washington or Oregon or any of the other bordering states that did actually provide sales offices for Ford?

Which DSO a car is ordered through has to do with the "region" (first digit) and "district" (second digit) that the ordering dealer is in. I don't know how Ford went about assigning dealers to which ever DSO they ended up.

I have ALWAYS seen that the first two digits in the dealer number is the DSO, that's why I thought it odd that the DSO on the door tags (actual and image) and the buck tag are 76 but the dealer number starts with 56. I thought that the dealer number would have started with 76 as well.

My 86 Idaho car also has a Denver DSO.

Do you know which dealer it was ordered through? (I assume the same one since it has the same DSO.) Do you have the original window sticker or invoice, or owner card (they sometimes have a dealer number written on them), or a Marti Report?

no Marti Report or Eminger on the 86 ISP. Kevin does not have the Eminger invoice however I will be ordering a Marti Report eventually.

Both my 83 Idado and my 86 Utah have the Denver DSO 76.

On Monday I will be talking with ISP fleet and get confirmation that the dealer was the same for all their orders.
