need help, converting from PS to manual steering box

I have a manual steering box, and pulled out the power steering box. I was trying to get the interface piece off of the power steering box to put on the manual box. Any suggestions on how to do that?

Also will the stock steering column work with this? its a 72 Plymouth Scamp. Automatic Column shift car, but we pulled all the shift mechanisms off and run a B&M floor shifter.

Thanks
