75 Valiant Power Steering.....

OK, I have a 1975 Plymouth Valiant /6 with Air. My stupid question of the day is, how the heck do you adjust/tighten the power steering belt.

I've looked at least 3 times, but, just can't find the adjusting bolt/nut, or see any kind of slotted hole which are normally found for belt adjustments of belt powered stuff like Alternators or Pumps etc.......

Aircon Pump is right over top of PS Pump, making it very difficult to see ANYTHING down there....

Haynes manual is pretty much a joke....

Any ideas or pics???
