Howdy all. I'm in need of some slip on towing mirrors for my 2006 1500HD. I have the power mirrors, and don't want to pay through the nose for the GM mirrors. I've done a couple of searches, but maybe I'm using the wrong search terms. I've found 'em for 2005 and 2007, but no 2006. Can anyone point me in the right direction?? Thanks in advance. Mike.
