Dana 44 axle spec questions

[4x4dodge]

According to Napa both driver and passenger side axle shafts are a 15 spline inner. After further research the Cad axle is a 30 spline inner and 15 spline inner then the sleeve to a 15 spline passenger axle shift. So that must mean the driver side is a 30spline inner correct??? That means the 3rd member is a 30 spline on both sides correct???
