All I can say is don't buy the ones I have (which is not quite the answer you want I know)

The wing mirrors look nice and met the size for IVA but the NS one was impossible to position correctly for the required viewing angles. They also don't move position very smoothly. I had to make up a nasty wedge block to tilt it inwards. Go for something with a decent length arm on it and plenty of movement.
For the rear view, again the area was fine but it was a bit short and only just scraped through plus I had to plaster it in rubber trim and some monster sized heat shrink to get it past the radius test.
I'd buy for the IVA now and pick for the look you want later and not worry about the extra holes you'll have to fill in the body
