Has anyone with a 1978-81 G-Body w/Cruise Master cruise control switched to Intellitronix digital instrument cluster and retained the use of the cruise control? I'm trying to decide on my options of replacing the dummy lights with factory gauges or the Intelltronix in my 1978 Monte Carlo. I still have the factory gauges that I took out of my '79 El Camino that I can use. Thank You!
