Hey Guys, I have been offered a gauge cluster from an 85 monte carlo column shift. I have an 81 malibu column shift and I am wondering how difficult the switch is, not from a "will it fit?" but more is the harness the same? My malibu has just the idiot lights (Right), and the monte carlo has analog gauges and a tach (left). I do plan on doing a bbc swap later so the tach is nice and will look stock. Any insight would be appreciated
