Newbie here starting my first A body
Welcome to the site and congrats on a good deal
I've been looking for a Dart GT to clone into a GTS and still looking for the right car
If it runs and drives then slowly do what is needed. It can be driven with rust in the 1/4 just check the front frame rails and transmission crossmember for rust.
Probably will have to change the wiper shaft seals, very prone to leak
Good luck, and we like PICTURES
