I've been looking around every where and cant seem to find a straight answer. I have a 91 k1500 Silverado, it has that ugly green rainbow speedo with no tach. What are some other dashes you guys have swapped into this year truck?

 

In 91' you could also get the newer style cluster with the tach similar to a 92-94'. From what I can remember, if you find a 91 tach cluster, it should just be plug and play. Otherwise you might have to do a bit of rewiring if you use an newer tach or go aftermarket (dakota digital, etc.). Good luck!
