This crossmember is a "double hump" design that simplifies installation of dual exhaust systems on Fox vehicles. The outer tubes are not welded to the center support, and thus can be adjusted to fit most engine/transmission combinations. It directly fits all Fox vehicles with a 4.5" dimension between the crossmember mounting brackets. It can be used on Fox vehicles with a 2.75" mounting dimension by relocating the brackets. It does not fit 1982 and later Continental or 1984 and later Mark VII, because they have a unique crossmember.

Ford Motorsport's transmission crossmembers feature a "double hump" design to allow for the installation of a dual exhaust system on Fox chassis vehicles. The outer tubes are not welded to the center support, so they can be adjusted to fit most engine and transmission combinations.
