Geez Douger.. you don't have any cool toys in your car at all do you?
I drive a Regal with HUD and tons of other cool things. No, Regals didn't have most of them as options. A little basic wiring understanding and any W body from 97-03 is cake. There's very little running on the serial lines.
Hud takes about 8 wires to get 95% of the stuff working.
Column should be a quick easy swap of about 20 bolts/screws. The dash likely has the wire in the connector for the radio controls for ease of wiring at the factory.
