To add a little more confusion, the 85-90 square bodies actually had six speedo options. I will try to sum this up as simply as I can.
US base - rectangular 0-85 MPH on top,0-140 KPH on bottom.
US w/gages - square 0-85 MPH on top, 0-140 KPH on bottom.
US 9C1 - rectangular 0-115 MPH on top, 0-200 KPH on bottom.
Export base - rectangular 0-140KPH on top, 0-85 MPH on bottom.
Export w/gages -square 0-140 KPH on top, 0-85 MPH on bottom.
Export 9C1- rectangular 0-200 KPH on top, 0-115 MPH on bottom.
"Gages" means you got a temp gage and either a "Fuel Economy" (vacuum)or volt gage, depending on year.85-90's never got a factory tach.
Some 9C1's had an auxillary gage pkg that included a temp gage, a oil pressure gage and a volt meter. It was about 2"x5" and mounted in the dash to the right of the steering column opening. The right side rear view mirror control was moved down a couple of inches to the sloped part of the dash and the mini cluster covered the opening that was left.
