Thanks for the additional arrows, I also felt my write-up may be a bit confusing.
As to putting the lever on the right or left, aren't these single lever/caliper sets made to go on a certain side? I know most levers are molded a certain way as to only go on their marked side (by molded i mean ergonomically designed to have your fingers wrap over the lever).
However you still can flop it to put on the other side.
