80 gallon deepblue rimless overflow position?

[baktabiznis]

Does anyone know the position of the overflow On a 80 gallon rimless deep blue frag tank (48x24x16). I need to know the measurements, the distance from the back left corner to the overflow underneath the tank and the left side of the tank to the overflow underneath. I need to make sure where I made the hole in the plywood topper is correct and will work for the system before I paint it????? Thanks

I know I need to counter sink the screws on the pic above.

Sorry for the sideways picture, I'm using the reef app and sometimes it does that.

My overflow is 6.5" from LR corner across the back and 8" from the corner to the Left side. It's an even radius, but Ido why it is not even on both sides.
