Hey guys, I've got a 1999 Malibu and it's got the stock radio in it now, normally I prefer a stock radio, but recently it's been giving me some issues. I'd like to put a double din touchscreen pioneer in it, I figure id go hard or go home lol, I know it's stock radio is like a din and a half, I was just wondering if you have any suggestions other than sanding the panel to make it fit, I've done that before but if there is a more "legitimate" way, any input would be helpful. Thanks.
