I THINK that the 5 bolt bell housing for a C4 will fit this transmission, but even if it does, you are looking for a hens tooth.
If you will google something like: "C4 bell housing" or "5 bolt C4 bellhousing" you will find a site that shows the pictures of the various bellhousings and the transmissions that they fit.
I have a 64 with a 289/C4 and in spite of the fact that I hate automatic transmissions and am a manual transmission person, find the C4 a very nice transmission for this car/engine combination. I also am not interested in changing the originality of my car.
In this application, the AOD would offer fuel savings(assuming that's what you're after) only if you run it long highway runs. Even then, how much fuel can you buy with the money you will have tied up in the swap and how much do you drive the car?
My $0.02,
