Clip-on/stick-on back mirrors

[Automahn]

Hi to all. Does anyone know where to get either clip-on or stick-on back mirrors? The clip-on I'm referring to is not the common one that is clamped along the edge of the rear tailgate but rather on the upper edge of the rear windshield (for those with flush-type rear windshields). On the other hand, I've seen 2 types of stick-on back mirrors. One like that on the older Kia Carnivals/Sedonas which is adhered to the upper edge of the tailgate and another type that sticks to the rear windshield itself (both with double-sided tape I guess). I plan to install a back mirror on our Chevy Venture without drilling holes or clamping anything on the metal part to avoid rusting. Thanks.
