Vacuum acuator years

My 4x4 actuator is no good and i'm hunting for a new one. i know i probably shouldn't be looking at used vacuum actuators as they are prone to failure, but i found a great deal on a used one (like 5 bucks). My jeep is an '89 and this actuator is off of a '93. Are the actuators off of the RENIX and the HO different, or will any year actuator work?

Thanks in advance,

89 and 93 transfer case vacuum switches are the same for the NP231.
