94RS instrument cluster?

Can you interchange a 93 z-24 instrument cluster (with all gauges) with a 94 rs std gauge (only water temp). They look identical from the front (size) but I cant see the back of the Z-24 cluster. I am not sure how many plug in modules there are on the 93, on the 94 there is the one female (long ) thats built on the back of the cluster that just plugs in the dash. And what would I have to do to make the gauges work? I figure i have to change the oil sender. The water temp should stay the same. As far as the tach? I would like to think that i can just plug it in and it will work. i dont know what you would have to add or change. Can anyone help? Is there a site that I can find if its interchangable? Thanks Tom :banghead:
