idle pully bearing blown

[matrix7531]

Sup guys i recently had a problem when I was driving my 1996 ford explorer because the idle pulley bearing exploded and ripped the bolt right out of the threads, I cannot thread the bolt back in so I'm going to need to find a replacement mount only I'm not sure what they call these things or where I can find one. I have a pic below of this mount which holds the alternator, belt tensioner, and idle pulley

Would It be better to just replace the mount or have someone re thread it?
