Thats correct, not that hard to do really.
And you only need a few RHD parts, Dash, wiper motor, steering colunm carrier, Steering box, PAS pipes and on normal Disco's a hub. On the Camels both OS and NS hubs have the bracket for the steering arm link bar. I bought a RHD disco with no engine or box and terminal rot and used that as a part bin.
