Finally decided to get Shag's new 9" housing out of the mothball fleet to prepare for powder coating when I discover (totally forgot, old age thing) that I have two threaded holes on the drivers side. Red has just one that serves both as a vent as well as a clamp for the brake distribution block.
Why would this housing have two holes? Maybe seperate holes for vent & brake line attach? Here's a pic
