cluster diffs

What the diff between a 96 Civi cluster and a 9c1? I know the 9c1's were certified, but is that the only thing? Buddy needs a 9c1 cluster, but i have a nice civi cluster already out ready to go.
Thanks

I 9C1'd my Impala cluster.

I don't know if there are any other differences besides the gauges.

The mileage is stored in the display module. This module is different between '94 and '95. I tried to swap the cluster and keep the display module but my problems seems to be with the display. On another car this method fixed my problem and I was able to keep the mileage correct. If it was my car I'd try that first.

Thanks Jim,

He doesn't care about the mileage, the cluster in there now reads 450k. Well did till it went out again. We'll do the civi for now.
