I'm sure you could make any wing work if you really wanted to.. I googled some pictures and the only thing I could find is this. I cant tell if the wing is from an sn-95 mach 1 or an old one.
it will add 50hp. Also put as many stickers as you can on the car and also neon lighting.....
Serious- welcome young man... enjoy the mustang.
However- you can try and make anything fit. In this case it will look hideous. Find a 93 Special Editon or Cobra wing designed to fit the trunk. Cervini's., Late Model Restoration, and American Muscle all sell them.
