Graham, 
Too bad you can't just take the 5.0 hose and the original hose and marry them...that what I did back when I still had original PS.  But...I think the fittings on the original PS hoses at the actuator and the cylinder are SAE Inverted Flair (IV) and the sizes will be in Imperial inches according to the tubing size...probably 1/4 inch and or 5/16 inch.  You can probably use AN with adapters.
Good luck, glad the project is moving along.  Send pix when you get a chance.

I have 92 foxbody p/s pump (it’s metric) and stock factory p/s (w/ long tube headers and drop bracket for cylinder).

This was my first attempt…I had problems flaring tubing.
The old hose was slightly too big for fitting…90’s vintage hose.
Used stock style pressure hose to control valve.




This is Barry’s setup from down under.
As I recall, he has the 94-95 accessory drive.



My current setup with Barry’s help (3 years).
The fitting in red was not needed, just in case line was too short.
Use stock style 65 pressure hose.

This is the stock style 65 pressure hose (Thompson pump).
