I know about the mouse click hopeing the aftermarket part will work,but yes try the one Camaro 69 above mentions if you put that part # in ebay shows that elbow 47054 pvc elbow comes up with a bunch at ebay so on ebay the part # an discription help $4.99 to 15.00,an your local auto store that has dorman parts should have it,for like $5.00 autozone should have it under that part #

 

thanks ^ copied and pasted the above also as an ms word doc As shown in the link craby gave, that's a discontinued GM part. So if you're having a difficult time finding one, Dorman part #47054 is the aftermarket replacement.
