never paid attention to the rear, but are they ALL the same design and mounting?

my 06's rear bumper got smashed in, so i'm probably going look for a good condition used one instead of getting it repaired at a body shop.

 

The 04-05 and 06-08 bumpers are not the same.

 

I'm pretty sure they're the same as far as mounting though, right?

 

I'm sure the only difference is cosmetic, but even if they mount the same, they're not interchangeable.
