I recently purchased a used gauge cluster from a 1992 z28 (145 mph speedometer) and plan to replace the one that is currently in my car (1992 RS 110mph speedometer).

Will it be a direct swap or are their other things that need changed? If so what? Additionally the person that I bought it from said that the odometer didn’t work. Is their a simple way I can repair the odometer and set the miles to match what my old gauge cluster reads? Or should I just try swapping the odometers?
