Be careful. Survivors are hard to come by. Try and disturb as little as possible. Don't replace the carb, get it rebuilt by a knowledgeable builder. Get the tank refinished if possible, not replaced - there are folks who can check the inside of the tank for rust and dip it in a solution that removes all scale and rust. Is the engine free? or stuck? Put the heads back on with fresh gaskets, change the oil, put on a new filter (save the old one if it is Mopar). Use a good zinc-content oil like Valvoline Racing Oil or Shell rotella. Remove the distributor and drill up the oil through the engine using an old mopar distributor shaft stuck in a high-speed electric drill.

Remove your plugs and spray a good loosening agent down the cylinders every day for three or four days. When you stick the distributor back in, keep the cap off and check that the points are opening and closing properly - if not, replace them.

When you go to start the car, have help - someone to prime the carb etc., watch points...

Hook up the battery and use booster cables on another car or a battery charger with a "helper" setting for extra help spinning over the engine - fast turnover speed is really important.

You're lucky. Sounds like a fun project. Survivors are a badge of honor, don't worry too much about the dis-colored interior, people will love it at shows because it's "patina"
