Check this guy out.He's a member of the Thunderbird forum I'm on and he made the set I got for my Bird (Fox body),and they are awesome.He does great work,and they were really easy to install...................
I dont see how its going to work, the fox Mustang only has a stand-alone single bulb turn signal. Unless somebody makes a totally different tail light housing that has three bulbs and is all red, then yeah.
i think it could be made to look pretty good if you used these tails from the 80s 4-eyed mustangs... i don't know how you could make it work on the newer GT, LX, or cobra tails considering they're oriented horizontally
these older tails are oriented vertically and you could probably make them light up a few at a time sequentially who knows, just a thought
