Alternator replacement

I am trying to replace my
alternator on my 2008 5.7. to get
to the top 2 bolts of the alternator
you first have to take two bolts off
of power steering pump and move
it out of the way. I got one bolt off
with no problem. The second is
another story. The pulley seems to
spin wer the edge of it is dead
center of the bolt. Tried swivels...
Extensions...... various sockets
through holes in power steering
pump just like the other bolt but
cannot get anything on bolt with
pulley in the way. Is thr a trick?
Will pully come off easily in place?
Appears to have Allen he'd screw
through pulley into pump. Why
would any manufacturer design
such a difficult way to do this!!
Hardest alternator I have ever
seen to deal with. Any
suggestions or any feedback from
anyone who have experienced this
before would be greatly
appreciated. Thanks!
