They recommend attaching the "fixed" side first, (the side that's NOT the one with the hinge and wires)
However, on my a7a266, it was such a tight fit, I couldn't get it on that way, and had to reverse the order I clipped 'em...
So I guess it doesn't really matter, just as long as you get it lined up right
EDIT: in reply to the other thread, I didn't reverse the clip itself, but the order I clipped 'em in..(wire side first)
