Rear Coil Over Shocks location

It is done to limit axle wrap as the axle wants to rotate in the opposite direction of tire travel. The way Chrysler assembled leaf springs (assymetrical with extra beef in the shorter front segment) acted as a sort-of traction bar. Using the shock to slow axle wrap is why they would be mounted forward of the axle. On some performance Fords you will see one shock forward and one behind. That is to aid traction and control axle wrap.
