Default pulley help please

My a/c tensioner and idler pulley seem like the bearing is shot on both of them. I changed the serpentine belt idler and tensioner pulley, but i can't seem to locate at any store that sells the ac tensioner and idler pulley. Can someone please tell me the part #. Thank you

Am i correct by saying the tensioner pulley and idler pulley are the same on the a/c belt system, because they look the same. On the serpentine system they are different, because 1 has ribs and the other 1 is smooth.

Correct -- the pulleys themselves are the same. But, for whatever reasons, GM sells the idler pulley as the pulley by itself, and the tensioner pulley as an assembly (i.e., the pulley along with the tensioner/spring device). Hence the two part numbers.
