G60 crank/power steering pulley required

[wbx6dan 10]

Hi there folks i am after a power steering pulley.

It looks like it bolts to the end of the crank pulley for the belt to run on,

now as im retro fitting the power steering and have had a quick look in the manual :study:

which looks a little like the crank pulley is in 3 pieces ! :bonk:

 

so are the pulleys the same or do i require a complete assembly help and purchase required please thanks Dan
