Getting that to work in a Mirada/Cordoba would also probably require the fuel injection to carburetor conversion kit that Chrysler made up to convert the Imperials to carburetors. It is probably doable, but might be pretty involved, as there may be a bunch of wiring involved as well.
If you are a big fan of digital dashes (I personally am not), it may be a lot easier to get something from Dakota Digital. I have helped a friend out in putting a Dakota Digital dash into a 1951 Mercury Resto-Mod, and it worked out well.
