4 door hard top. Flat top. No center pillar and the doors are clean with no window channels and a flat roof. (no such thing as a 4 window hardtop) It uses the sleeker front glass of the 2 door hard top and convertible.


4 door hard top, Riviera sedan or 6 window hardtop. Just a different style top as the flat top was considered radical and there is a serious lack of head room. No center pillar and the doors are clean with no window channels. the triangle windows in the rear give it the 6 window designation. The 6 window uses sedan glass from the 4 and 2 door sedans. The windshield is much more verticle and about an inch taller.

This is a 4 door sedan. No 6 window designation, just a 4 door sedan. Center pillar, and window channels.

The 2 door hardtop or coupe. more of the same no center pillar or window channels.

My hearse is built off a 2 door Sedan. You can see the difference in the rake of the front glass.

Big difference in head room.

rear overhang.

More rear overhang. The lack of snow shows how much it hangs over.

Some flat top advice. Never park it under trees. The flat tops love rust and suck debris under that rear window trim and it rots the seam.
They also like to leak and the floors love rust to. There favorite spot is between the front and rear side windows. Also they suck stuff into the doors. Keep the holes under the door clear. A lot of 59-60 Chevrolet parts will fit your car as well. keep that in mind as it is usually obtainable and cheaper since it does not have Cadillac written on the box but it is identicle.
Air bag it and give it a good interior. Shaving the trim would look real good. You don't have to worry about ruining the car or any of that crap. I own the 2 holy grails of 59 Cadillacs. I have a 59 Convertible, I am dropping a 72' Eldorado 500 in it and I also have the 59 Miller Meteor. Only 88 were built like it, I see a future Ecto 1. I don't care what other think about it either. If you don't ever want to sell that ends the argument, build it how you want it. If any one gives you crap about modifying the flat top tell them what I am doing and make them cry.
