10" brakes on formula S cars?

Remember the old saw - Never say never with Ma Mopar. Lots of stuff got ordered that wasn't on the order form, and lots of stuff ended up on cars coming off the line that weren't on the build sheet. I kept wondering why I kept coming across 1972 6 cylinder 4 door Darts and Valiants with 8 3/4 rears until I realized it was the last year for 8 3/4 A-bodies and they were dumping their stock.
