how do I replace compressor housing 18G

Okay so I have a crack in my inlet and just got a new one. I cannot tell how to get it on or off for that matter. The 2 bolt holes are for the wastegate actuator so how does the housing attach to the turbo?
anyone have a how to? Pictures
what am I missing.

here is the new one:

 

There should be a giant C-clip holding the housing on.

 

sweet, I figured from the groove that it was something like that. I was about to go pull the td04 from the engine in the garage.
thanks Matt.
any special tools or just find a way to squeeze it to pop it out?

 

i have some snap ring pliers you can borrow

 

Rick I completely forgot about the c clip ring. My bad man.

I got my neutral switch today BTW.

 

those damn c clips. Dont put it on backwards or it wont hold.
