C4 X BRONCO DANA 20 T/C

Advance Adapter

Our Ford C4 adapter to the Bronco Dana 20 is 7.375 in length. The adapter material is 356 T-6 heat treated aluminum alloy, and the adapter has a provision to retain the original early Bronco mount. The adapter kit includes an adapter housing, new C4 output shaft, alignment retainer, snap ring, gaskets, seal, o-ring, vent, fastening hardware and adapter instructions.

Even though Ford used this transmission stock in vehicles from 1973-77, stock parts are no longer available. We manufacture a new aluminum adapter housing and a custom output shaft that is identical to the original Ford C4. This kit uses the stock Bronco spud shaft which may need to be shortened in some applications. No driveline modifications are required when replacing a manual 3 speed that was originally mated to a V8. The automatic shifter can be obtained from either 1973-77 Bronco, or a B & M cable-operated sport shifter can be used, PN715680.
