Here is my two cents worth-and that is all this is worth
. I assume that you have matched up the old wood to the new physically next to each other. Just to verify dimensions and hole placement, But the floor piece you have in next to the original looks to be off in hole placement. Maybe it is just the way the picture is shot. Also, the middle vertical piece looks to be about three inches to short. Again maybe the it is in the picture.
