I've been entertaining the idea of removing the landau top from my Eldorado, and I've read that aftermarket ones can come off while the factory installed top is almost impossible to remove. I'm not afraid of doing some paintwork if it's needed. I'm curious to know if my top is factory or aftermarket, as the RPO codes didn't give me much insight. My top stops at the end of the rear windows, and it has chrome trim that runs all the way to the front of the fenders. Does anyone know if this style is dealer installed?
