[T2] Alternator Cooling Boot on 72?

[John Garland]

I've purchased an upgraded alternator from BNR Parts and notice it has a
hole in the side that my other alternator did not have. Does anyone know if
the 72 has a cooling boot? I did not see one when I last replaced my
alternator, if not what is that hole used for?

Here is a link to a picture.
