Other than that they were similar to the LT230 found in the DI. The E brake linkage was more rudimentary that the one found in the DI and a PITA to remove.

The main reason the RRC gave up the LT230 was the need to add distinction to the model what with the introduction of the Disco in 1990 MY. To maintain the upscale quality of the RRC the Borg Warner was added. Being chain driven it was quieter and smoother than the LT230. Plus, just like with the DII and the loss of the CDL, Rover obviously thought the upscale Range Rover customer had more important things to do than to bother with such pedestrian activities as managing the center locking differential.
