Here's a heads up! If they R&R the rear quarter panel make damn sure they use a rust inhibitor on the welds BETWEEN the wheel well lip!
I had to have the right rear 1/4 panel replaced and questioned the shop about what they would do to make sure the new panel didn't rust. They said they rust proof it and there won't be an issue. Well the truck goes back in on the 25th to repair rust between the lip :M .
The left side (OEM panel) with 139K has no rust the new almost two year old panel is rusting out at every weld on the wheel well lip. Get whatever they say in writing and make sure they cover rust for as long as you own the truck! What a PITA this has turned out to be!
Good luck
