Fitment & Compatibility

This kit requires the specified new-style Big Ford rear housing flange with a 2.50-inch axle-flange offset. Measure between the wheel-side axle-flange face and the housing-flange face as the axle worksheet directs; it is not the rotor-hat offset. Stock 1990 Lincoln Town Car compatibility remains unverified. Confirm the actual axle before relying on the vehicle entry below. One-piece 11.00 × 0.81-inch iron rotors contain the parking hats and work with included internal shoes. Cables, clevises, cable adapters and flexlines are separately supplied. Verify flange diameter/chamfer, the 3.06-inch rotor center and the supplied 2.80-inch register adapter. Studs larger than the clearance holes may require machining. Nominal 14-inch wheel guidance remains conditional on the drawing.

Listed models: Town Car. See the supplied table below for each year, submodel and equipment condition.
