eshopps slim overflow leaking!

I bought a used 75g rimless from a buddy of mine and it came pre drilled with the overflow installed, I cleaned the tank up and cleaned the overflow and inspected the seals, everything looks good I placed the gaskets back in the proper order between the wier and tank and between the nut and acrylic box. I just can't seem to get them to stop leaking, it's just been a constant drip every few minutes from between the tank and overflow box it's self. I'm not sure what's going on, if I need to seals if anyone has any idea or suggestion let me know

Easy to overtighten gaskets. Hand tight, then 1/4 turn.
