We saw someone post up this info and decided to share it for those considering switching over their stock powermaster brake system to the hydroboost setup.
This isn’t a how-to post, just a parts list (plus where he got the items) and a brief explanation of what the writer did with his own install.
[credit to whoever it was, we forgot to write it down]
[this is not a recommendation to switch over to a different type of braking system, just a FYI for those who are thinking about it]

I had to drill out the hydroboost to brake pedal so it would go on the brake pedal. The lines need to be bent to fit.
Out of the pump, originally, the line goes forward towards the steering box.
Now the line needs to go behind, aft towards the hydroboost.
There’s a brass fitting that comes out of the top of the power steering pump that came loose instead of the line fitting.
I had to cut the line, take both out and separate them in a vice and reuse the brass fitting.
I really took my time doing this.
The return line was not used because it needs a sharp turn coming out of the steering box so I reused the original return line (with a new o-ring installed) and used a 3/8″ brass tee because you now have two returns – one from steering box and one from the hydroboost.
