I got no pics
but
I can tell you what to look for
It is a piece of sheet metal with an edge that runs 90 degrees of the hb
or
It has a metal edge that will line up with the marks on the hb
Seems like it has a hole in it before the edge
It is not all that hard to see if you ask me
I'd say it is missing or maybe you just did not look hard enough
