LEft (USD Drivers) is convex and right(USD Passengers side) is magnified, that plus you have to shim the screws that hold the mirror motor in place on the left side to get more of an angle for both mirrors or it wont move enough. if you want to see what I mean go sit in the passengers side of your car and try and adjust your mirrors as if it was a RHD car, the mirrors will reach a limit before you can see properly and thats how much or how big of a spacer you will need to put on the right side of the motor. To remove the plastic push the mirror so it faces up (looking up and pop off the plastic slowly from the bottom, theres a clip that holds it down at the bottom , then user a heat gun and a suction cup to remove the glass from the plastic or remove the glass first then remove the plastic.
