yeh i feel for you neil1112. i bought a set of mirrors from US ebay as well and found out that it creates a problem in terms of visibility (i can see perfectly fine on the passenger side, but not the driver's). basically i have to lean forward to be able to get full visibility of the driver's side mirror.

mine are powered, so im stuck wid em until i buy proper RHD ones.

moral: dont buy side mirrors from US (or any other country) unless specified for RHD.
