I was at Ron Ayers today, they have a 2015 standard and a 2012 side by side. Took off both seats and the basic platform (seat base?) is the same. the 2012 has metal attachments about midway, the 15 does not. the place to mount the attachments and the hole for the bolt is there, just not used. Because of the metal attachments we did not try to cross-mount them.......but I betcha it would work.
