Like a lot of people, the gauges on my 2003 Cav have gone haywire and I can pick up a set of gauges from a 2003 Sunfire for a reasonable price. Although the lay-out of the gauges is a bit different, I'm thinking that they should be interchangeable. Has anyone done this who can tell me definitively whether it will work or not before I tear my dash apart, install the gauges, reassemble the dash, and find out that it doesn't work?

00-05 Cavalier and Sunfire clusters are all interchangeable
but you will have to do the passlock relearn. HERE
