I brought this topic up a couple years ago on the board but I don't recall if there was any definite answer. I have a 91 Z28 with the 110 Speedo Gauge cluster. I want to know if it is possible to swap out the gauge cluster for the for the 140 Speedo cluster. If it is what gauges might have to made. I searched through the archives but I think this convo was too old. Thanks

I just swapped out my 85mph speedo in my t/a for a 120mph. you have the electric gauges so all you gotta do it take one out and put the next one in. real easy. and no calibration is necessary(spelling) if you don't take off the needle

 

Now all I have to do is find one. Also when you swapped out your gauges did you notice how they gauges were backlite? I am not sure if I want to go with white face gauges and wasnt sure if you could change the color of the back lighting.

 

once you get the gauges out you'll see how its lit up, its easy to change the colors

 

Twist I have the cluster from my 91 b4c if you need one, make me an offer. Its 145mph
