The driveshaft is the same for both transmissions ('11 to '14). The front and rear connections are bolted connections. The transmission end does not have the old-school splined shaft connection to the driveshaft. There is a length adjustment on some driveshafts (pull or push one end in to get the dimension [I don't remember exactly what it is, sorry] in their instruction sheet).
SVTPerformance members have a discount code at many of the vendors - could save you a few bucks if you ask the vendor.
