31 spline axle upgrade- What is necessary

For those of you who have performed a 31 spline axle upgrade is their a link or a previous thread that list the required components? We plan on removing the rear end for a gear upgrade and really wanted to get a head start on sourcing the components. At the end of the day I'm sure the best thing to to is to take it apart piece by piece but I wanted to give this a shot first. My car uses the 8.8 rear end. Below i what I have purchased.

*Motive rear gears

*31 spline Eaton Tru-Trac Diff

*the rear end rebuild kit from Ford.

*I have contacted the Drive Shaft shop for the 31 spline axles.
