Might need to check on the 1" from the edges. How large are the holes? If I'm reading the drawing correctly, you have the holes one inch "on center" away from the edge. That would put the edge of the tank and the edge of the hole very close. Is this one inch from the tanks top trim? If so, then that would be good. I can't quite read the number from the edges, but if it's only 1 inch I would move it in more. This is only my opinion - which I'm always willing to give
