Note the slanted edge of the rear most side windows. That should make it obvious that the middle windows will not fit.

They did make sliders for the rear but they are relatively rare. I have a set, imported by a fellow enthusiast, for the left side. Although they are available for the right side as well, it's is not recommended for fear of decapitating someone or injuring a hand sticking out that window when the sliding door is operated.

GW does offer an aftermarket version. However, people have reported issues with proper sealing. I do not have personal experience with the matter.

Another alternative would be to have one made. There is a vendor on Samba offering this service. Pricing is about the same as buying one in Europe, in my recent experience.

Perhaps you are confusing window interchangeability between the left and right middle windows. People have done that but the seal between the glass cannot keep water from seeping in at speed. The opening ends up facing the airflow.
