My car came with an aftermarket LCA which was fixed and had the coil spring and shock like you see in the pic from the manual in Chicagowil's post. I purchased the coil over kit (Pro Shock) from CRII before they shut down and deleted the coil spring perch top and bottom. The new coilover supported the entire weight of the rear end of the car on the two bolts the original shocks were mounted with. I was never a fan especially when there was about a 2" spacer/shim holding the coilover out enough for the spring to clear the chassis. I redid the coilover mounts in a double shear design which takes so much weight and stress off of the only thing holding up the back of the car...the two bolts per side. Simple idea that required fabing some brackets for the top mount and installing new brackets to the Currie rear end when I upgraded to the 9". I made the brackets using 1/4" plywood and hot glue, and brought the mock ups to a welder/fabricator and he made them from steel. They are held in place by two 3/4" bolts, I hade to add the second hole. Pictures are available in my gallery. I still have the mock up and could have more made if there is any interest.
