Hi SoloVoyager, sorry you've been waiting for a reply.
If your suspension is the same as a US-spec R51 (2005-2012) Pathfinder's, then the quantities given in smj999smj's original post are correct for the front end. 4 of each part number is the right amount for the complete front end.
I had to replace all 4 lower control arms when I did my lift due to seized bolts. I used Mevotech aftermarket lower control arms from RockAuto.com on all 4 corners, and the Nissan caster/camber part numbers smj posted.
***Please note, when replacing the rear lower control arms, only 2 complete sets of parts were required in total. I ordered 4 as required for the front, but had 2 sets left over.
To summarize:
These quantities will provide caster/camber bolts for the complete front end, as smj999smj states in the original post:
Pin assy., Nissan P/N 54580-7S000, Quantity: 4
Disc eccentric, Nissan P/N 54559-1Z600, Quantity: 4
Nut, Nissan P/N 08918-6441A, Quantity: 4
If you want replacement caster/camber bolts for the rear end as well, you'll need 2 more complete sets of the same part numbers, making all "Quantity: 6".
In the US, 2005 Pathfinders came with the front caster/camber kit installed from the factory, 2006 and later did not. All years (2005-2012) of the R51 seem to have the rear bolts included from the factory, though.
Hope that was helpful!
PS Very jealous that you have a diesel! Neither diesel engines nor manual transmissions were available on R51's in the US.

Very cool!
