Jeep GC steering box swap...

I found this info on another site. This may be an option for you as well.

No adapers needed, just install a Metric O-ring syle output fitting in your PS Pump and use O-ring lines. I think the O-ring lines/fittings are superior and less likely to leak.

I got a PS Pump output fitting from a late 80s S-10 PU (I think it was an 86) and installed it in my stock PS Pump. Just took the old fitting out and the S-10 fitting threaded right in letting me use an O-ring line on stock PS Pump. Depending on what year your car is you might be able to buy a later pump that has the O-ring fitting and use the whole pump. Mine is a 68 with the round/oval neck on the PS Pump so I had to retain the original pump with just the newer fitting installed.
