I have a 1990 5.0 LX Convertible. We had a 5.0 Mustang a few years back, and right before it was wrecked we purchased a suspension set. We have in our inventory 4 suspension components. The two front shocks, and two large rear shocks. What were trying to determine is what exactly the extra shock or strut is located at the rear end. It isn't the main shock, were pretty sure of that. It is another shock that comes off at a 40 degree angle away from the axle to the frame at the rear of the vehicle. Whats this component called? can someone link me to where I can purchase them individually? Thanks.
