Using older Power Steering pump with newer box. Lines question.

[Wildman65]

So I'm converting to power steering on my '65. I have a pump that is the older style. I'm wanting to say it's just like the one I had on my 1972 C10 years ago and I have the box from a 1984 model. I'm sure somebody else was in my shoes, just checking what my options are. I'm going to take it to a Hydrolic place this week and see if he has anything to make lines. The '84 lines on the pump side (well the pressured line that screws into the pump), won't screw in due to different size fitting. The return line shouldn't be to big a deal except I can't use it because It was all corroded and twisted off. Hopefully my rambling made sense.
