The light stuff is vacuum boost, some of the heaver light stuff is hydroboost. In the middle of the med duty there have been some air over hydraulic, now hard to get repaired. At the top of the MD there is air brakes. No parts to fit air brakes to light stuff.

I hear rumors of an air brake compressor for b Cummins and have seen one - without the PS pump, don't know if both will fit in the space.
