For anyone who may need it in a future
I'm gonna answer my own question

Correct way of fitting the propshaft to front differential :

Brand new M8 ZNS3 Bolts with ribs x 4

Torqe 20Nm
Tightening Angle 45deg

So torque down to 20Nm using torque ratchet and than rotate another 45deg using standard ratchet.

Good luck
