Hi John, I used a RHD memory seat, stripped off the cushions, then mounted the motors on the opposite side, and fitted the mounting for the seat belt pretensioner on the opposite side also.
The latter being the trickiest if you don't have welding gear.
I then modified a passenger side switch skirt to accept the memory switch, and fitted a LHD eight way switch pack courtesy of Trikey.
The end result is a memory heated cloth seat in place of the manual one, my mother presses a button to position the seat into the most comfortable position to enter or exit the car, and presses another to move the seat into the most comfortable for travelling in.
I didn't take pictures as this project evolved I'm afraid, however the end result looks like this..........
