I am looking at a 1988 Monte Carlo that has a round speedo and idiot lights for the rest. What is involved with swapping the cluster to one with real gauges and a tach? I know I have read it here before but cant find it again. Please help me in this. The car has a 200 4r in it and I plan to swap the 4.3 for a 350 and make a cruiser out of it. But I still want gauges to keep tabs on vitals while on the road. Thanks, Michael
