I was scraping my tow mirrors after an ice storm this weekend and pressed too hard on the glass and it cracked (don’t make fun of me I was desperate). Turns out I’m an idiot and my truck has heated mirrors (always wondered what that button did). I would prefer to just replace the glass on the mirrors but I’m pretty sure that the tow mirrors are after market and I can’t find the glass that is shaped like them. Anyone have an idea of what website to check? Or do I just have to get a whole new mirror assembly. Your help is greatly appreciated ?? (Below are the mirrors I have)
