well, that could cost quite a bit. Has the suspension been checked out? the brakes? steering? and if the rust is pretty bad, its hardly worth it in my opinion. The other stuff is going to cost a good bit, but remember, on a 1977 car, there may be a lot of little things that do or will need replacing soon, which could add up really fast if you don't do you own work. I would expect to be ready to pay at least 1,000 in the first while for repairs of old and worn out parts...that is unless the previous owner has fixed a lot of things. Your choice...good luck!
