compressor removal

1981 cj7 with 258/4.2.  i'm trying to remove a/c components from the engine compartment.  the compressor is mounted on a bracket on the passenger side of the engine that holds the a/c compressor on the top of the bracket and the alternator on the front of the bracket below the compressor.

how does one remove the compressor from the bracket? does the whole bracket need to be removed in order to remove the compressor?
