Good question...If I remember correctly some parts are interchangeable with early 5th gens, not sure about 2013's they might be the same tho. I curious to see if someone else can shine some light on this.
You can swap any strut from an 03+ 4Runner, 07+ FJC or 05+ Tacoma with each other. The only difference you'll find is the springs rates might have changed from one vehicle to another.
