I did get those bolts undone. I loosened all of the other bolts on the fender, and pulled it so it slide forward just enough to allow the door to open. Then I locked the finder in place by tightening a few key bolts, so that it would not slide back. This allowed me to open the door and access the 2 final bolts.

The most annoying item was that the rocker panel had to be removed also, which was much more difficult than I expected. I ended up breaking half of the locking clips with my clumsy movements.

Once I had the fender off, I inspected the chassis and the frame. From the underside of the vehicle, everything looks ok. There is definite crumpling of the top of the frame in the engine bay, just forward of the battery.

I actually got everything back on and re-aligned to compensate for the crumple point, so only the trained eye could see that something is wrong. Still, the front right and rear left wheel gaps are asymmetric, so I'll be taking it to a body shop next month to see about getting the frame stretched back into place, relative to the body mounting points.
