Hey guys. This thread helped me out while replacing my antenna and antenna ornament yesterday, so I figured I should post another helpful tip. I recommend not removing the fender liner. I thought I was prepared with spare clips, but at least in my 2012, I would have had to remove/break clips behind at least one painted panel. Too much risk for me for an antenna repair. For me, it wasn't the top or bottom of the ornament that needed to be trimmed, but just the sides (the part that goes inside the panel of course). Applied dish soap around hole, heated a bowl of water for a minute and forty seconds and dropped ornament in to soften it up. Then it popped right in, nice and snug.
