The only 140 speedo that directly replaces the 87-88 85mph speedo is the 89. They changed the design in 90 to accomidate the airbag or something like that.
I bought the face kit from JEGS (Speedware Kit). Painted my needles with florescent orange paint. Othewise it was hard to see the needles during the day. Sent the whole pod to Brothers and they re-calibrated the speedo( left the odometer alone) and returned it to me. Took about a week or so. They were real helpful on the phone. Do a Yahoo search and find their web site.
