Found it though it maybe a stretch In Chapter 386 Page 11 Itachi says that the Nine Tailed Fox attack happened 16 years ago And the first chapters of Part II Chp 245 250 onward states that Naruto Sakura etc were age 15 and that 2 1 2 years have passed Also Oro trying to get Sasuke s body was suppose to happen exactly three years from the end of Part I and that happened several chapters back
