driver side speaker grill
 

This morning while cleaning the inside glass in my 03 SS I put about an inch-long crack in the driver’s side speaker grill. You really can’t see it from the outside my concern is it may crack all the way across. Should I go ahead and buy replacement grills or do you guys think it will not get any worse. I don’t drive it much but sometimes sits in the hot sun. the car has less than 37k that’s why I baby it so much. thanks to all..

BTW if I need a replacement does anyone have them for sale? I'd need black..
