Strangest thing found in your A body???
A mouse had gotten into the radiator of a 73 Duster. I picked out piles of wet globs of fiberglass insulation and the shells from about 20 walnuts.
My mom had a car one time (non-Mopar) that all of a sudden started making a terrible racket everytime you turned on the blower motor. Turns out, the mice had stored so much dry dog food in it that the fins from the blower were stirring them around!
