I found a cheap and easy solution at Walmart.....about $1. Small, pie shaped stick on mirrors for the corner of a regular car mirror. I mounted them on a small shaft and suction cup and attached in the upper left and right corners of the windshield. They are adjustable, so you can set the angle to suit your needs. The left one is great as it is quite close to your eye and with a quick glance can show whatever is in your blind spot. The right one works ok, but as its further away doesn't show quite as much, although still good for that blind spot on the right rear.
I am not adept at posting pictures here, but would be happy to send some pictures if you want to email me at
