I modified my original mirror on our 1990 plus 4 passenger side door which was completely useless, by simply making a hardwood wedge the shape of the base which was thicker at the front thus moving the mirror head position inwards. Finally painting the wood to match the door. I needed to purchase a longer oval head woodscrew for the front. This worked well for many years until I decided to fit Librand's stainless bases retaining the round head mirrors I fitted from a Honda van. I retained the wood wedge although the new bases are slightly different in shape so I intend to make a new wedge. How anyone can drive on the continent with the standard mirror set up is taking a huge chance which was the main reason for fixing the mirror. One thing I did find with the new bases is that is that to adjust the arm position you must wedge the arm from the base following the instructions included to obtain the position you want, you cannot just click the arm around as with the original ones.
