New to me 71 Dodge Dart

Saturday I picked up a 71 /6 auto Dart. It's going to need some work before it can hit the road but I think I got a good deal for what I paid. It runs and drives but needs a gas tank (good used one included) and all systems checked and gone through mostly the brakes. I popped off the M/C cap and found brown brake fluid. Worst part of the car is rust just below the bottom corners of the rear windows.
