Seems I was a bit off after further review of your pictures. Your blower (thrower ) has 4 attachment bosses, and my bracket only has 3, so my bracket will not work without modifying. I did notice that your blower dose not look like mine either, so I would question if you have a different year. I think you have an earlier model than what I have. For instance, my blower has a gear driven chute turret, and yours has a cable. My blower is from my 1969. You may want to scope out the manual section of the forum.
Here is a pic of the blower bracket for my application.
