That sounds odd, because the microfilm shows all cars getting the 
breather heads starting in '72. Are you sure those heads didn't get 
"lost" in an early valve job?

Look at the cooling tin. The tin that came on those engines had holes 
and rubber grommets where the hoses leading to the breather tubes 
would have gone: just to the rear of #2 injector and in front of the 
#3 injector.

Your '72 is carbed, isn't it? I don't know where the hose from the 
breather box went on those engines. The microfilm shows that you got 
the late breather box, but that the PCV valve was only for FI 
engines. I didn't know that. But the microfilm doesn't show an 
alternative part for the carbed engines. There HAS to be something. 
Otherwise the breather box just has an open hole on the underside; 
there's no way to connect a hose to that.

What's in there and where does it send the breather gases?

This is looking like some errors in the parts list.
