OK i think ive found it.  http://www.bodykits.org/  makes custom body kits.  So im talking to them now to make a new bumber for my mach.  Same style as normal.  GT bumper.  But instead of  "MUSTANG"  it'll say "MACH 1"  i should here back from them in a couple days or so.  They may need at least 6 orders to complete it.  Not sure if they'll make an exception.  Send me a personal message if your interested.
