Probably not helpful in the slightest, but LNBs will work upside-down (looking from the front of the dish), I had (still have actually!!) a heyuuuuge Grundig Twin LNB on my indoor Hispasat (30w) dish, and the dish had to be pretty close to the window aswell as being low in order to pick up the signal, so the LNB had to be inverted with the cables at the top in order for the dish to be low enough...
But anyway, yes, the Cable/Socket is the "Little hand", pretend you're the LNB and look towards the dish, turn the LNB clockwise to 7 o'clock, tighten up the nuts/screws and you're done, well, for the LNB skew you are...
