Type 44 alternator cooling?

[Steven B]

... memories!  

I dug into this one many years ago for my 5kCSQA.  I suspect my car may have been in an accident as it didn't have the duct.  It was possible for me to buy the part that goes from the alternator rear cover to the bumper, but even all those years ago the part in the bumper was NLA.  

I think there is value to adding a cooling duct that runs up to the back of the grille.  It would be even better if you could have some sort of funnel at the inlet to pressurize the feed.  
On the V8Q the alternator cooling is plumbed into the front brake cooling duct in the belly pan.

There was a "air gatherer" of sorts which clipped onto the lower section of
the bumper... I'll check and see if my parts car still has this.
