The rust is along the roof drip rails, the driver side passenger floor, the hood at several locations, bottom of the drivers door and a few spots around the sunroof. I might post a few digital pictures in the next few days. It had not seemed to cost effective to put significant $ into rust repair and repaint. Now the engine further calls the $ question. I will begin to take the heads off this week, but this is a very low priority.
Thanks for the input.
