73 dart power steering box/ check valve??

not sure what it really is but there is a piece that bolts onto the power steering gear box that has a fitting for a hose. The new gear box I bought did not come with it so I had to remove from old one. when I looked at the back it looks like there is a spring in there, my question is, does the spring need to be lined up with the hole. It looked kinda of cock eyed in there. I just want to make sure its in good condition before I reassemble. Is this assembly sold. I couldnt find it.

Thanks guys
