Are the carrier assemblies the same for the automatics and the manuals on the G37 Coupes?

Do all G37s with manual transmissions come with a limit slip or VLSD?

 

I'm pretty sure all the manuals are sport packages so therefor they all have the VLSD.

 

That's my thought process as well. What about the housings? Why do the 370Z guys say the housings are different between the autos and manuals? Why does the FSM have two different sections, one for the manual and one for the automatic rearend?
