Need help!!! 1965 power steering nightmare

Yep that's the wrong pump and your missing the return line nipple on the box.

He has the low pressure return nipple but might be missing the high pressure fitting (can't tell even blowing it up on my phone)- might even be broke off!

I have a nice factory box from a 67 which has the earlier smaller pitman arm spline than the later box.

If you swap to Sedanman's box, I'll throw in the 67 pump (just pay the shipping). Don't have any mounting brackets or cap but someone is sure to have them.
