The '65 Monza I bought in '67 had the LM closed caps with tubes that went to 
the two hole grommet aft of the battery tray.  My '65 Corsa has the original 
two hole grommet.  The phosgene gas issue was only on the EM Delrin fan cars as 
you indicated.  I was told the vent tubes kept the hydrogen gas from 
accumulating in our sealed engine compartment to avoid an explosion AND that it kept 
the acid droplets caused by an overcharging alternator from corroding the 
wiring, carburetors (especially our plastic choke pulloffs).  It could be that 
corrosion problems with EM's were a lesson, but the LM fender insulation on all 
but the 500's kept the acid away from our fenders.  The '76 Chassis and Body 
parts manual lists Group 2.345 part 3909114 (Two required) as the caps for our 
batteries.  It also lists 3863987 for the HD battery that had different spacing.

I make sure to vent my batteries whenever possible to avoid the corrosion.
