1989 data file is up (4th post down the first post) - as you can see in this screen shot I've broken the ORBAT down into the respective formations, where units do not change (i.e. Army Air Corp Regiments) I've left those named, the others you just need to research the names of the units within each Division or Bde.
Each unit is tied down in terms of TOE so all you need to do is select the unit, enter the name and away you go. This should save scenario designers quite a bit of effort if your looking to create historical groupings, you can still select (further down) BAOR battalions with Bde/Div elements.
