They will fit 05-20.
Some venders have that parts break in 08, but that was just for grill/headlight/bumper related things, not the floor. The only thing you need to worry about it whether or not they fit the Pro4x with the subwoofer.
There are changes in the hooks in the floor, some years have two hooks, others have one on the driver side. However, I'm not sure what years are different. So yes, there is difference, beyond the models designed for the Pro4X with the sub.
