97 Cobra AC compressor help needed...

Hey guys... I am having a problem with my AC. The pully has a front plate on it and that plate is loose.. It is rattling badly It does not seem to affect anything but I cannot find anything with pictures or information about it. I have found replacement compressors but none have the pully assembly with it so I have not idea if I have lost something or what I should do...


any help please!!!!! I do not want to hurt my baby...

thanks
