Dang it Fred
Apparently I like starting fires.
IF you are welding muffler hangers to the bottom of the car, be sure the back seat is out and you can remove the black tar stuff that MOPAR used for seam sealer on 72 models before you start welding. It will catch fire and then the seat and then the rest of the interior all before you can get the water hose back on and pulled to the garage.
DON'T ASK ME HOW I KNOW.
Evidently, they used the same stuff in 70. I was using a torch to notch the frame rails for inboard spring hangers. I wonder if your back seat looked like mine.
