The Front window is actually an entire replacement mechanism and motor, for the manual set up, and would not physically fit into the rear window housing. I enquired at several motor spares outlets when I was looking to replace my manual windows, and they all stated that there was no rear kit available. One VW modifier informed me about the Audi motor/band method, but I wasnt entirely convinced with it. I think it may state it for rear as the motor would be universal, but the mechanism would be front/rear specific.
