Changing an alternator belt on a 350

[thedudeabides86]

Hey gearheads! So, I might have a silly question. I've got a '72 C20 with a 350 motor in it. How do I go about changing the alternator belt easily? Is that even a possibility? I changed my belt last night and had to loosen and separate the PS pump from the block to get around the PS pump belt, so I wouldn't have to remove the fan assembly. Am I making more work than I need to? Luckily the third bolt holding to PS pump to the block is too long and allows for a little wiggle room. I've posted a couple pictures below. The first picture with the circle shows the two PS pump bolts at the front. The second picture shows the third PS pump bolt that is a PITA to get to and is too long because by the time I realize I did finally get it tightened down, I was fed up with it. Any advice would be super helpful.
