Ordered and just received 4 new burner bowls for this unit. Had no problem removing the old bowls but the mounting screws do not match up between the new bowl and the bracket to which they are attached. Any way to resolve except to drill new hole in bracket? and why don't they match up? Have only tried one but I am assuming that they will all have the same problem. I certainly do not want to go to expense to also replace the brackets and it appears they may not even be available.
