2 quick questions re: 440 reassembly

Oh, I forgot to mention, both of the nipples go up on top of the water pump housing, where I have them now, but they might be reversed. The front hole in the water pump housing is for an EGR coolant sensor. Do I have the nipples reversed in the picture?

So I'm pretty sure I can remove the front A/C compressor mounting bracket and use it to mount the P/S pump. I may cut it down to size first.
