YES keep the original dash gauges . they can be rebuilt . There is a romance when looking at the original gauges . You can find a more modern dash in the newer car you drive as a daily driver KEEP THE OLD CARS ORIGINAL
I would take that huge beltline door top chrome from a DeVille convertible and put it on this car for some extra bling. I don't know why the DeVilles had the extra chrome but the Eldorado didn't. Not a fa of the rims.
