This unit is for 28 spline half shafts and is perfect for replacing your existing worn out TL or great as an addition to a car that came from the factory with an open differential.  The following cars came from the factory with an open differential and can be retrofitted with this new TL unit:

All '93-98 Mark VIIIs

All '94/95 Tbird SCs with automatic transmissions

Many V8 Tbirds/Cougars from '91-97...check your axle code on the door and use a Ford shop manual to decode if you have a TL unit installed or not.

NOTE:  When using the aluminum housing that came in the Mark VIII you will have to chamfer the casting boss as shown in the picture on the side where the ring gear bolts up for proper clearance.   This is not necessary on the cast iron housings.

These units are rebuildable with an inexpensive new friction/steel kit that SCP can provide.  The manufacturer recommends the use of high grade Non-Synthetic GL-5 gear oil and LSD (Limited Slip Differential) additive for long life and smooth operation.  The use of synthetic oil is not recommended and may result in aggressive or noisy operation.
