The write-up provided in the link above describes it pretty spot on.
That bracket does have to be removed, with the engine supported.
Follow each "arm" of the bracket, and you'll find its corresponding fastener. On the other end (frame side), where the mount attaches, there are two 15mm bolts that hold the mount to the frame (underneath the mount on the frame rail). Rather than taking out the long bolt in the center of the mount, take out those two 15's and just remove the entire assembly. It'll help clear out some elbow space...
The P/S pump can just be unbolted (three 13mm's behind the pulley) and moved aside.
