The 91's are all electronic, they should just drop right in

Welcome to TGO, midnight. Since many questions have been asked and answered, I search is generally a good idea. FYI: 82-89 clusters are mechanical, 90+ electronic.

Really? Because the cluster in my '89 is electronic too. And I switched from a lower-rated speedometer to a 140 with no problems. And the 140 speedometer was out of an '88.
