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.
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.
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.
