Digital dash in '91 Wagon?

I have a '91 Caprice Wagon with a 305 in it. It has the stock speedo cluster in it. I found a digital dash out of a '91 9c1 and the heater control with the "Low Washer, Fuel, Oil, Coolant" warning lights. Will either or both of these work in my car. I'm not sure how different the 9c1 wiring is and if mine has the right hookups. Thanks.

i asked this about a year ago, and the wiring is supposedly really different, they said it could be done but its not worth it
