83-86 Mustang taillights are the same regardless of trim level. The only ones different were the SVO units and they were still the same lenses but with the addition of 6 horizontal 1/16th inch stripes. They were Red corners with a red lower reflector. Turn signals were next up top and were amber lensed, then white/clear for the back-up light. The 1993 Cobra used 85-86 SVO tail lights.
87-93 had tail lights that had a red corner with the lower red reflector. the upper bar was clear/white with one bulb (turn signal position) being amber and the other (back-up) being clear.
87-93 GTs had the 'Cheese Grater' tail lights, which were ALL red except for the upper inner corner, which was white/clear (back-up light). The lens was cast with the 'grater' detail and it should be painted the same color as the car.
To answer Caseys question; to make a fairly accurate (body) 87-93 LX Hatch, you could start with cutting the Coupe at the body styling line (from the door casing to the tail lights and across the roof from the aft of the door case to the other side) and graft the same section from the AMT 87-89GT Mustang to your roofless Coupe body. Being different manufacturers, they will not match up precisely but will work. You will have to modify an MPC SVO lower spoiler to make it an LX unit. Use the GT quarter windows. You will use the Coupe kit tail lights.
For the interior, the 87-89GT will give up its 'hatch' tub (and steering wheel if you want an 87-89. If you want 90-93, use the Coupes stuff) and rear seats.
