I have ordered shock absorbers of the same make and part number that have been on my car for years. The shock absorbers are the same brand and part number but different lengths. More than an inch too short won't work. If you don't have universal lowering springs on your Mustang, don't waste time, they won't fit. Had to pay for return shipping and then AUTO TRUCK TOYS was charged for restocking! Lakewood should have left the shock as is, or at least changed the part number.
