Rear Coil Over Shocks location

Brad, you are correct. Leaf springs are an inexpensive method of mounting and controlling the rear end, but as found in many cars (symmetrical - same length front/rear of the axle) they are prone to allow axle wrap and wheel hop. That's why Chrysler leaf springs work better. Trailing arms (which ladder bars and other setups are) work better as far as axle wrap (and are more tuneable), but need more pieces to keep the axle located side-side properly.
