It's not critical, looks to me as though the Westfalia people
eyeballed it on mine.  My passenger side one is 1.2 inches down from
the headliner edge, 1.2 inches aft of  the point were the door edge
molding begins to turn forward, same distance above and forward of
the coat hook as the slider curtain snap is above and behind
it.  Driver's side is similar but not matched as well.  Is that good
enough for you?

Yours,
David
