The backrest bolted right in with the Reach seat, but I had to make some modifications to the backrest anchor (adjustment assembly) to move it back the roughly 2" when I tried to remount the stock seat. A little reading enlightened me that the SG seat moves the rider back about 2".
I'm watching this thread to try to keep myself up with the excellent advice you guys are posting regarding the SG/TG/XXX differences. I undoubtedly will at some point want to add trike package to my SG and retire my Voyager kit (for no particular reasons).
