Rear spring hanger/shackle info?

[Locomotion]

Are they all the same or are there any differences between an F-body rear spring hanger/shackle and those from M or J bodies?


Just realized that I should have put this in the Chassis/Suspension/Wheels section.

My research shows there is two different kinds of rear spring shackles/brackets (rear portion) on all FMJ vehicles.

The front hanger appears to be the same on all FMJ’’s.

The rear shackles and frame brackets are the same – unless car came from factory with rear sway bar (think police).

All but

With rear sway bar (police)

Strange that a rear shackle would have anything to do with a sway bar, but I'm no engineer. Thanks.

My guess it has to with the side to side motion - which is when the rear sway bar would be in effect.
Think of how hard a police car is driven.
