'91 & '92 Z28 Speedo have 145mph?
Does the '91 & '92 Z's have the 145mph speedo? If so will they work in a '91 RS? Anyone did this? I know the older ones have them, but in '91 the whole dashboard changed. A picture of a '91 or '92 Z28 dash would be nice too. Thanks, Bobby

L98 camaros came with them. BTW, the clusters changed in '90. I have just swapped 145mph in my RS. No problems, but the tach is not working properly. I don't know if the tach is bad or if it has something to do with the swap, but I am going to use the tach from my old cluster.

r90...did you swap the entire cluster when you swapped the speedos or just the speedo itself inside the old RS cluster???
and did anything need to be calibrated with the swap?

For those of you swapping out your 115's for the 145's, this is only a plug and play operation if your car has a V8 from the factory. If you have a V6 car the tach is gonna be off, as it was set to check on 6 cyl instead of 8.(I luv to cut and paste)

If you have a 90-92 V8 Camaro, than the 90-92 145 MPH gauge cluster is a direct swap, everything will swap over and work correctly.
