Bell housing modification is required on all original (1964 1/2-1970) and late model bell housings to adapt the Borg Warner “standard” and “World Class” T-5 SROD (single rod overdrive) five speed transmission to an early model Mustang, and to utilize the stock clutch linkage.

The modifications required, when using an original (1964 1/2-1970) bell housing, are to drill one clearance bolt hole and drill and tap a second bolt hole to attach the adapter/spacer plate to it. The spacer is required because of the longer transmission input shaft of the T5 transmission, and also adapts the T-5 mounting bolt hole pattern to the original bell housing.

If you do not intend to use the early model clutch linkage and are opting for a cableinstallation, you can use the late model bell housing and late model throw out arm as they are, without any modifications required

Caution note - Always check the condition and fit of the crankshaft pilot bushing, since some T-5’s have a smaller diameter pilot.Problems such as clutch chatter and popping out of gear will occur if the pilot bushing fit is not correct.
