Hydro boost

[fully]

I’m building a 53 merc truck and I’m using a hydro boost out of a 99-04 mustang, and GM type II power steering pump and a MII rack and pinion. I’d like to convert it over to AN fittings and lines but having trouble tracking down what fittings I all need. I still have the hard lines that come off the hydroboost and I’m wondering if I should take them off right at the pump or this connection circled in res

Im not familiar with hydroboost conversions however since there are various assortment of fittings and connections wouldnt it be better to remove from pump? Might make it easier idk depends on the space you are working with
