Thanks man, no wonder I couldn't find it it (radio section lol?!). Ideally I would make my own but I figure after tools and materials it'd be cheaper to buy an oem one. The generic ones available to me locally look out of place. Again, thanks for posting the PN.
It's P/N 65311730952. My car could use one, too (it's breaking in the middle). My understanding is that it's a ground strap which helps reduce RF interference with the stereo, but doesn't affect anything else. You can either get the OEM part, or you can find generic ground straps at many auto parts and/or hardware stores, etc.
