The turf saver rear end in my 2008 700xtx busted and is over a grand to replace. Seen the rear ends for the 2011 and 2012's are less than half as much. I understand they are not the turf saver and that is fine even better. My question is will they mount in my 08 The front half all the way to the pinion are identical. I also figure i may have to change the axles. Any help on this would be appreciated.
