the LHD/RHD is a metal sort of... lever type jobby, same on yours? It's actually labeled on mine, is a little hard to see though. They arrive on the wrong setting so you should probably have changed them :p
The issue with mine was similar, the left/right adjustment ball joint thing was broken tso the ball joint just comes loose from where it should be rather than adjusting. Hopefully the replacement set won;t have the same issue. When I phoned them they said that 3 out that match of 5 had been returned for the same reason.
I'll try to remember to take a pick of the LHD/RHD switch when I change them next.
