Dumped the powermaster system. After upgrading to the Blazer brakes, it uncovered a leaking powermaster system. Here are pics after the install. The downside is that there is a low pitched humming sound from the pump/hydroboost system. I also had to move the stock reservoir forward by about an inch to clear the new Wilwood MC. My ps pump is about a decade old. Probably needs to be replaced. First going to experiment with different feed and return lines and make sure all the air bubbles are purged from the ps fluid.

Hydroboost booster looks like the one that came on 1984 and early 85 Turbo Regals.
Or at least that is what I put on mine. Works great.
