Will tbird a/c box fit in a mustang March 17, 2010, 12:31:11 PM Hey guys I know this isnt for a bird/cougar but the part is from a bird :D and I need to know if the A/C box that goes behind the dash will fit in a mustang. I bought a mustang parts car and the stupid thing was ordered w/o a/c . I need a box so I can put my dash back in the car.Thanks guys,John Quote Selected
