Not exactly a Fox body, but I have all kinds of custom interior parts for 89-93 T-birds/Cougars that came out of my 91 Cougar. I have a console, dash trim, custom speaker pods, and many other things, check out my sounddomain page for a full listing and let me know if you are interested. I'm really wanting to get rid of this stuff and if you're local, I'm willing to make a better deal to get it out of here.
