I want to take my black air conditioning vents out and paint them silver so that they match my pedals and wheels. I can't get them out though! The center ones are stuck, I got the side ones out but the center ones won't come out! I pried at them for like an hour and they won't pop out, they just get stuck, and now one of them is stuck sideways and I can't get it back to normal even. HELP! :?
