One last update on this. I dug up the two different style bolts that retain the a/c bracket. Each one is 4 5/8 long. Did some more measuring and came up with the dimensions shown on the attached diagram reflecting this 4 5/8 length. It looks like a 5 5/8 length bolt would bottom out on either hole in the block, so I used 4 5/8 to attach my a/c bracket. Not sure why parts manual would specify 5 5/8.
