Randy, I don't have any clue, but I'd bet it works about the same. You could verify that by opening up the access plate and watching it rotate. If you pull towards you (left), the 915 linkage rotates away from you (top of coupler moves right). The principle that makes that adjustment work ought to be the same.
Or if it isn't, at least you've got the bump, and someone who knows better will slap me around for being an idiot.
(But then you'll have an answer, which is the point...)
