'94 3.4 Squeaky pully! Which one???

Sup guys, got a 94 3.4 camaro thats gotta last me until I can sell it to get my dream car...an LS1. So that being said, my engine has been squeaky lately, thought it was a belt at first, but narrowed it down to one of two pullys ( i think).

I just dont know what these pullys are on the 3.4 So heres a pic so you can help ;)
