Hydroboost hose to a rack and pinion ... hose to -6AN fitting?

[G-NUT]

1984 Suburban. Stock PS pump. Stock hydroboost. I've installed a Mustang 1979-93 rack and pinion. The kit came with a return hose and a pressure hose, but the kit is designed for a convensional / non-hydroboost GM saginaw pump power steering system. I'm wanting to retain my hydroboost system. I need either a hose that will connect at my stock hydroboost unit and go to the pressure port of the rack OR some sort of connector or adapter to connect my stock hydroboost hose to the pressure port of the rack.

From what I've been able to research, all I know is my hydroboost hose has a 16mm fitting on one end and an 18mm fitting on the other (haven't been able to clearly identify which was at the gearbox). Also, the rack and pinion came with an adapter screwed into the rack that is male -6 AN fitting.
