Replacing rear bumper

My rear bumper on a 2008 Tundra was replaced by a repair shop a couple of years ago and it is already starting to rust. I would like to replace the bumper with an OEM quality bumper. Does anyone have a suggestion on where I can order a decent bumper?

 

Looks like Rock Auto has a decent price.

I plugged in 2012 because that’s what I’ve got. Should be the same for an 08 but you may want to navigate through and double check it’s the same for yours.

Also, it may be worth it to check with the body shop about it. They are supposed to replace the parts with an OE quality part. I don’t know what “a couple years”
Is to you but I don’t think your bumper should be rusting this quick.

 

Why don't you just remove the bumper, have it sand blasted and powder coat or line-x it. Any new one is just going to do the same.
