A:
If you look at the feather from the back to the front, a left wing feather will look like the letter L and on a right wing feather it will make a back wards L. You will want to match the wing of the feather to the helical or off-set that you are putting on, right wing feather with right helical clamp and left wing feather with left wing clamp.
