Can't find part numbers for A/C pulley assembly
 

Hello fellow G owners.
I'm trying to find the part numbers to replace the bolt and shaft only for the A/C Idler Pulley.
I'm driving a 2005 G35 coupe AT. All the diagrams that i found seem to show the pulley and the belts only.

For your reference below is the picture that show 3 parts assembled (pulley, shaft, bolt)
Can anyone point out the part numbers for the shaft and bolt only and suggest where i could get those?

Thank you!
