Thanks Ed, from my "googling" it looks like Ford switched from a dual front mount in 2006 to a single mount like what is shown in the rendering (8L2Z4010A). I'll see if I can find that earlier part number.
Update -
... even the earlier 2002-2005 axles (5L2Z4010BA) show the single mount so I think maybe the source info. (not you Ed) is incorrect on what axle housing that is. I believe the info you posted came from here -

"We use a donor rear end from a 2007-2010 Ford Explorer (some 06's work but it appears that there may be a half model year split, you want dual front mounts)"
Turns out the above may not be true.
The Wavetrac sounds pretty good, I think I'm going to do it
