| Re: 1991 RS Air conditioning system on a 1991 Z28?
They are the same.
The only difference in systems is the change from v-belt to serpentine which, doesn't apply to you and is somewhat useless information.
The Z will have dual fans as opposed to the RS having single but, if the Z's wiring hasn't been messed with (A/C simply unplugged and removed), you should have no issues hooking up the 'new' from the RS.
