Will the 89-91 gage cluster work in the 86-88s?

 

Not perfectly or smoothly. The automatic seatbelt A-pillar is a little wider. Nothing a dremel can't cure. Plenty of people have them on, but the ones that look good, had to do some shaving. Oh and that i know of there aren't any 89-91 specific models.

 

You can get 86-88 on pieces from autometer I think. The 89-91 can't use them due to the seatbelts.
