Hey JuanR, certainly understandable to be scared on halloween but not of a refrigerator... It is only a machine... I've seen some replacement parts that are different than the originals but usually they were adaptable... Go to
http://www3.sears.com/ and input your model number... Search your model and you can find some pictorial diagrams of the parts breakdown... Hopefully this will help you figure out how to put your chute back together...
In the words of Papazian - Relax! Don't worry! Have a homebrew!
