I found these at Walmart for $3 a pair. They are adjustable, and I mounted them in each upper corner of the windshield with a small threaded shaft onto a suction cup. The left one is relatively close to your eye and fills in virtually the entire blind spot on the left side. The right one, being further away, does a decent job of filling in the right blind spot, but not as comprehensive as the left.

They look like a factory installed mirror....that is the comment/question I often get from people looking at the car.
I am not good as posting pictures here, but send me a private message and I will be happy to send along some pictures.
