how do you attach the top of the alternator to the bracket or block

What is your question?

Replaced the alternator/voltage regulator and belt. There was no where to attach the top of alternator to anything. the belt tensioner was adjusted and was tight. there was noise and then tension was loosened seemed ok. Now charging light flickers on dash. I went to dealership and was told care requires a top mounting bracket that bolts to block. But bracket and bolts are no longer available. So What can I do? Any and all answers are much appreciated. :)
