mustang hydroboost fitting sizes?

[unimogger]

I am getting around to hoses on my mustang hydroboost. Three fittings on the booster, two of them have a short hard line adapter.
I have measured them, and looked over a few thread charts but am still not 100% sure on any of them. Any help is appreciated.
The fittings at the booster are two different size ring/ tube fittings like the steering box. The return is a small banjo type fitting.
The adapter end of the short hard lines are metric, maybe 16mm x 1.5 thread count and use an o-ring at the fitting shoulder.

This info may or may not help you; these are the fittings I used to mount a 1999 Mustang Cobra Hydroboost to a 1973 EB with a 4x4x2 power steering box, converting to AN fittings in 2017. The Cobra (and GT, I believe) has a metal “block” which redirects the return and steering box hoses (see image below).

RonJones, thanks, my fittings were a little different than yours. Not sure what model mustang this came out of, but there are hard lines instead of the adapter block. Booster fittings are 5/8-18 and 11/16-18 o ring. The stock power steering box is 5/8-18 and 11/16-18 inverted flare. Here are the adapters I’ve gotten to make them all AN-6
Still have the return on the booster and the pressure line on the pump to convert

Some good tech at the bottom of this page too, including various versions between Mustangs.
