Upgrading to some T5/T56 transmissions could require a new bell housing to match. Ford Racing and Quick Time have the perfect bell-housing for your application. Dont forget your bellhousing spacer plate that is sometimes worn or missing. 5.0 Resto also has all the bellhousing bolt kits, transmission to bellhousing bolts, bellhousing dowel pins, and pivot studs you need to finish off your transmission install. These bell housing and spacer plates fit 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, and 2004 Mustangs.
