[Odd Job]

I've had a quick look on fleabay, the non dimming mirror looks much smaller in both actual size and the part that goes to the screen.

I'm guessing that the way they fix is totally different.
It might not be a quick and easy swap over, it may be a bit more involved than I hoped.
I dont really want to destroy the self dim, as I want the option to change back if I have a change of heart, or when I sell my vehicle the new owner can put it back to how it was.
