gauge cluster swap

I was wonderin if anybody had swapped gauge clusters from one without a tach to one with one. I have a '94 with a v6, and a friend gave a a cluster from a '94 with a v8. Everything looks the same on the connections, but I want to be sure before i attempt it. Thanks

Good luck. I am wondering the same thing (nearly) and no one seems to know. One of these times, I am just going to try it and see what happens.
