Is it possible to swap out a digital dash cluster out of an 88 or 89 z24 into a 90 z24 with analog gauges? If so, what modifications need to be done to make it work? I put a digital dash in my 90 z24 and there is no plug for the speedo wire, and the tac does not work. Is the computer different from a digital dash and an analog dash?? Please someone help!!
