This might be a little too late but they are both infact interchangeable. My base Prerunner came with a solid window and I upgraded into a sliding 4 piece rear window instead. I love it, I generally drive with the windows down on cooler days. Btw... there is NO adhesive that holds it in place, just the weather rubbber and all it take to remove the whole window is a flat head screw driver and five minutes of your time.
