I picked up an 88 n/a here recently. Well today I found out that there is a pretty good size rust hole on both sides of the car on the rear portion of the frame. I didn't get a close look at it to judge how bad it is exactly. But from what I understand if the frame is rusted the cars basically screwed. Is it worth actually getting under the car and attempting to repair the frame, if so how? Or should I just run it until it dies and not waste dumping more money into this car?
