First post on here. Got a 2013 FX4 back in August and this hasn't been our week. Boss back his hitch into the bumper and today I broke the mirror. I'm looking at replacements but can't find any info on whether or not the 2007-2008 mirrors would work. I found some that are similar but I'm going to lose memory and auto-dimming function. But everything else is pretty much what I have now, plus the passenger side is going to gain the wide view corner mirror. (don't know the proper name) So would anyone be able to tell me if they used the older mirrors and whether they worked or not? I would appreciate it.
