Here are some pics of my Fine Molds Y-wing with the Trialliance 2-seater conversion. I relocated the top turret to where the droid should be so that it could fire aft giving protection from attacks to the rear. Sure would have helped in the first attack on the Death Star! The Trialliance conversion was very simple. One word of caution. I had to cut a “sunroof” in the clear plastic to allow the pilot to fit. The rear seater monitors systems and uses a targeting computer to site the rear firing laser cannons. She took a Silver at the recent Wonderfest.
