I am attempting to replace a power steering pump on a friend's car,

I am requesting a diagram and instructions for the process

The new aftermarket pump looks the same, however the pulley is an inverted bolt with hex key head size 3/8" with no budge, are these usually reverse threaded?

It looks like there are two different types of power steering pumps. One pump, the pulley, is pressed onto the pump shaft and do not unscrew. The other unscrews I don't think it is reverse thread. Make sure you have the correct replacement pump, here is how to change it out in the images below. Check out the images (below). Please let us know what happens.
