Front CV Boots -Inner and Outer?

[colinmi]

This probably a very simple question. I'm getting the parts together to freshen up the suspension of my 2012 Legacy and the CV boots are on my "while I have it apart might as well" list. I see all of them listed except for the outer front ones. They are shown on the Subaru parts diagrams but no part number is listed for them on the sites I have searched. Is this because they are the same as the inner ones? I would think they'd be at least a little different as in the rear.
