now that ive taken a quick look at the pics, you will need to cut out a lot. multiply what you see in the pics by 3-4...and thats how big that rust is... or even bigger. u have a lot of work cut out for you if u decide to go through. I suggest not doing it and either having a shop do it or sell the car. you will not have a good experiene with this. if you dont do it right, that rust WILL, i repeat WILL come back. remember that.
