I think what Dallas4u means is to put those little stick on wideangle mirrors on your sideview mirrors, I did and now I have eliminated all my blind spots. there seems to be little circular or square ones

Buy them at any auto parts dept or store, then using masking or scotch tape on the back of them to temporarily test their location onto your side view mirrors and sit in the truck to determine if that where you want to stick them for final placement. then peel off the backing and paste them to your sideview mirrors !!

Works great!!!
