I don't have a picture of the new style, but here is the picture of my alternator with the broken bracket.
On my boat the bolt failed not the alternator flange, a new grade 5.2 bolt was only 3 bucks or so, I am afraid that a grade 8 bolt might cause the flange to fail as in your picture. Your top bolt looks to be stamped as a grade 5.2.

I will order the bracket as it seems to recognize that the either a bolt or a flange will fail.
