power steering fitting sizes

[454HO]

Anyone know what size fittings fit the output of a mid 80's power steering pump and the input to a hydraboost booster??

I know it is either 18mm x 1.5 O-ring or 16mm x 1.5 O-ring, but I forgot to measure when I was at the shop yesterday. I need to get the fittings ordered asap so I can make a up a AN hose. They look like this:



FWIW, if you ever do a non-standard engine transplant, do not expect to splice together two power steering hoses with a barbed coupling and hose clamps. It won't hold, and when it lets loose it will spray hot power steering fluid everywhere. Yes, I speak from experience.
