Can someone please tell me how to get the Ign switch out of the dash on a 68 CHevelle?? Its been about 20 years sinse I have done it and there has been way too many beers, shots and other stuff that may or may not be legal. So I could really use your help. I am trying to remove the plastic part that houses the inst. cluster and heater control. I have every thing else off except for the Ign. Switch. I know it has something to do with the little hole next to the key hole and turning the switch to someplace. Any help would be great. Also has anyone ever put a tach in where the square Chevelle thing is between the speedo head and the oil, alt. fuel gauges??
