The ball of paper was the master cylinder rebuild kit.
Here's the old SERIES II vac next to a new SERIES III vac. Other than a simplified control valve they appear to be identical (size wise). Some of the hookup locations are different... nothing insurmountable.
The place I got the vac from included a rough hookup diagram and an exploded view for parts ID. May have to fab up a bracket or two.. no biggie. Lots of 1/8th in steel laying about.
