As far as I'm aware, the seat mountings themselves haven't changed from 93-11. Although that being said, extended cab / single cab still matters. Single cab seats will fit into an extended cab but not the other way around.
Somewhere around 05, the passenger seat got some extra electronics, such as a weight sensor for the airbag. If this isn't present on yours then don't worry about it. However if you do have it, your replacement seats will need to be equipped with this also, lest your airbag light go on and throw a code.
I know in 03 they have an extra sensor to see if the passenger seat is buckled, much like the driver's seat. Look around under the passenger seat, see what you find.
