Here's a couple pix from my recent rebuild. The first is prior to installing splitting california. Two pan head screws hold the back part of splitting cali with one of those on the wire ramp. The forward screw is countersunk so it's flush with splitting cali and it goes through the plastic, through the end of the wire ramp and into the tall threaded post. It's pretty blind putting this thing on while getting the moving part of the mech into the slot on the bottom side of splitting cali, so tricky.
I may have other pix if these aren't good enough.
