Roger, go to PEP BOYS, they have a couple of mirrors that are convexed. They are about 11" long and will clamp right on your dash mirror. I bought one and it is great, you see everything from your back fenders side to side. Also, if you have side mirrors pick up a 3.5-4" dot convexed mirror and put it on the passenger side mirror. You will see everything from the back fenders forward
