The Hydroboost was the easiest thing... I got a rebuilt unit off a friend for free (Chevy Astro I believe) and ordered a mounting plate / socket from Talon hydraulics. I went to earls and got the fittings I needed as well as the Lines.
Bouchillon Performance was the source for the GenIII Hemi P/S pump fitting to -6AN. I made a fitting for my P/S gear box. Details given below.
These fittings allowed for the entire P/S hydroboost system to use AN fittings.

I went with a -6AN x 1/2-20 for the pressure line and I believe a -6AN x 11/16-18 for the return... this is the one that needs to be drilled out for the relief spring so protrude into...
After Drilling...
The drilling was done on a typical drill press - nothing exotic... then I just drilled down as deep as i needed.... I measured the depth of the old fitting and found it is goes until about the mating surface between the fitting and the pump itself... so I drilled the new fitting accordingly... not rocket science.
