Mirror / linear pattern help

Hi all,

Ok, I kinda messed up my design intent and now brains stopped working! Ive attached the part so hope it makes sence, but basicly I want to mirror the "roller" detailing about the centre line I put in, and then mirror those top two down to the bottom two holes if that makes sense??

When I made the model I did so with the centre line through the holes rather than between them. Otherwise I would of simply mirrored about the plane. Ive tried putting in a sketch plane but still no joy.

Hope its as simple as I think and im just being very stupid!!

Thanks
