Hi I recentally bought a 2000 eldorado and I love it I was tore between it and a 99 seville. I really liked the Seville's instrument gauge cluster or whatever it is called it had a nice light and when it cranks it is cool and can show digital speedometer, anyway wondering if one would fit my eldorado and what all i would have to go through as far as getting mileage right or speedometer working.
