Thanks Mike. That's something I failed to consider. I was originally going to shape some convex mirrors to sit in the lower corner of the quarter window inside the car. That would give me a clear view down the side of the car, but they would be relatively small in size and wouldn't be adjustable. They would be solid however, so that may be the way I'll go. I'll still have some time to try them out before the bodywork is done, but I can see how flimsy they are just sitting in the drive. Perhaps, that's why they weren't on the car when I bought it.
