I was looking at a TJ soft top install today, and saw that the rear window connected to the back with a "rolling" movement where it locks into the grooves, I took a look at mine to be sure that I had something similar. I have a metal bar that runs across that the rear window slides into. I'm pretty sure the replacement video was on a TJ, but it might have been a JK. Do all TJ models use this sliding type? Or is it not OEM hardware?
Unrelated: Have to replace the soft top because the dealership sold it to me saying it was "practically new", I knew this was a lie when I could clearly see popped seams, and restitching on the windows, also with a broken zipper and would not fix it anything. They are really hard to zip, and one zipper is actually on backwards. I don't like KIA anymore.
I can upload photos if needed.
