Advance Adapters

The Ford NP435 & T18 adapter the Bronco Dana 20 is 7.50” 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, alignment retainer, snap ring, gaskets, seal, o-ring, fastening hardware and adapter instructions.


Transfer Case


The adapter assembly will fit any 1966-77 Bronco Dana 20 transfer case. This adapter will only work with the “T” style shifter. Transfer cases with a “J” style linkage will require modifications to retain this linkage.


Transmission


The kit is designed for exclusive use with the Ford NP435 & T18 4 speed transmissions, 2wd version with a 28 spline output shaft. The NP435 cast iron case length is 10.875” and has a aluminum top cover. It was used in Ford trucks from 1964-85. When using our adapter kit with the NP435 & replacing a 3 speed manual in a V8 early Bronco application, the transmission conversion will not require any driveline modifications.

The Ford T18 cast iron case length is 11.875” and has a cast iron top cover. It was used in Ford trucks from 1967-84. The T18 is 1” longer than the NP435, requiring new drive shafts.

These truck transmissions are a very popular choice for the early Bronco drivetrain. The kit includes an adapter housing, alignment retainer, seals and gaskets. The kit utilizes the stock transmission 2WD output shaft (28 spline), and the stock Bronco spud shaft. The adapter housing is drilled for both the 2WD NP435 & T18 transmissions. Both transmissions will require some floorboard modifications to allow proper floorboard clearance. A sheet metal shop can fabricate a new tunnel cover plate to accommodate for this larger transmission. The stock shifter handle will most likely need to be modified.
