Plz help, finding a brass coupler for steering box pressure line on '67 273

I'll post pics in a second. Help me out here. The pressure line on my '67 'cuda was leaking, so I went and bought a new one, went to put it on, and when I tried to attack it to the steering box, the brass fitting there stripped out. The pressure line I bought came with a brass fitting, but isn't the one on my box. The one on my box has an l-bend in it, and is shaped like a cube (as in, it's a brass cube, with one end connected into the box, and perpendicular to that, is the pressure line end, sticking out of that cube). I can't find this part anywhere, and I'm starting to feel like I may not have the right steering box on the car.

My descriptions sound awful, I'm going to go out there and take a picture, one minute.
