Is this the correct orientation of this type of negative plate?
The above photo is NOT the correct orientation of the negative plate.  This type of negative plate fits into the air spring, left stanchion with the wide open side facing up into the stanchion.  One clue it was wrong (I installed it as shown in the picture--upside down) was loss of travel. When the fork is put together, I had just 100mm of exposed stanchion, when with a 100mm travel fork, about 110-115mm of  stanchion should be showing.  I went in again, having to pull the lowers and drain the oil since the negative plate can only come out the bottom of the stanchion as the route thru the top is blocked by a narrowing of the inner diameter of the stanchion above the negative plate's seat.  So, I flipped the negative plate around, put the fork back together, and it now shows about 113mm of stanchion and there is 100mm of travel to bottom out now.
