I got this antenna housing for my 2016 chevy spark ls. This is the second time I broke mine, this time my dumb self backed into my garage too soon while the door was opening and hit the antenna mast. The dealer charges 200+ to replace it (Henna Chevrolet in Austin Texas). So I figured it can't be too hard to replace so I got this, thinking it's not oem, exactly what came with the car but I was wrong, it is literally exactly the same, I didn't realize General Moters owns ACDelco. Got it on yesterday and can't even tell it's a replacement. All you have to do to replace is remove the three retainers in the headliner right by the back door, halway remove the trim on the sides and stick your hand underneath the headliner to get to the single bolt that hold in on.
