Factory Rear Sway Bar...how rare?

good catch dusteriffic! i have done some more digging and this is what i came up with. dodge and plymouth for it's final year in a bodies offered a special police only package for the 4 doors. with production code A38. The A38 Dart had the highest-specification components and systems from front to back; suspension (with a rear sway bar), brakes, cooling, electrical, and powertrain systems were all maximum-duty. The engine was Chrysler's 360 in³ V8, with an A727 TorqueFlite transmission. Production totals were low, with most A38 Darts were sent to the Los Angeles Police Department and the Ventura Police Department in Southern California. so technically the a bodies did have a rear swaybar option, but it was only for police use and never offered to the public. the f bodies got theirs in 1978. this bar will fit the a bodies as well. i suspect it is the same bar as the 1976 police bar just with a different part number on it.
