FYI - from the ford-trucks website -
https://www.ford-trucks.com/forums/1...e-6-0-a-7.html - a 6.7 starter fits on a 6.0.
The benefits are that all three bolts are the same size - m8-1.25x40mm - and a 6.7 starter should be available far longer than a 6.0 starter...

I bought a new Ford starter (SA1004 {#BC3Z11002A}), and the parts above, for less than the Mahle starter from CNC fab, and plan to install once we get the van back. If I remember to take pictures, I'll update this thread.
RockAuto has Ford starters for ~$300, and they have a 2-year warranty vs. a 1-year warranty with Mahle.
Also, per the ford-trucks thread, the 6.4 and 6.7 starter requires more amps, so upgrading the battery cables may be even more advantageous.
Just providing some alternatives...
