Prius (2004-09) :: 2006 Rear Brake Self Adjusters Forks Not Symmetrical

Well, I took the rear brakes apart without paying close enough attention. My problem began when I noticed the rear brake self adjusters' forks were not symmetrical. Although both have a deep slot and a shallower 'shoulder' between the 2 tines of the fork, they are different depths and the 'tines' are different lengths, so there are four ways to reassemble them: both deep slots positioned toward the dust shield, both deep slots positioned away from the dust shield, deep slot on the starwheel end positioned toward the dust shield with the deep slot on the other end positioned away from the dust shield, or deep slot on the starwheel end positioned away from the dust shield with the deep slot on the other end positioned toward the dust shield. I've seen photos with the adjusters in place, but the slot positions are not clear. I've seen photos of the adjusters off, but no indications of how they fit on the shoes. Can't find a diagram or instructions anywhere.
