Upper Ball Joints

[NobleSteed]

Does anyone have a definate part number for the upper (front) ball joint for an M400 (build 180)?
I understand that there were 2 fitments but that the later cars had a bigger Joint? Pretty sure it is from the strut of a Peugeot 605 and is a screw in fitment. Only asking as the Dealer I use seems to be taking a while to get back to me so might be quicker to order from Peugeot

Cheers
