Last Thursday I received a phone call from the engineer that is making the upgraded parts. He wanted to ask me couple of questions regarding pinion B. When I asked him when would they be ready his reply was "soon".
As you know, these guys haven't been very accurate with their estimates when it comes to timing, but I will phone them again tomorrow.
He did go on to say that when disassembling the pinion, you should be very careful as they could be easily damaged.
