Dart positions on Knees?

Nocturne

Active Hunter
I have a pair of BM knees and some metal darts (from someone here, but curse my lousy memory, I can't remember who).

Anyway, how far apart should the center of the darts be, and how far up from the bottom of the knee should they be?

On BM's knees, aren't there indentations or something to show where the darts are supposed to go? Or is the front "panel" completely smooth?
