Heavy duty Forestay Extender not fitting through bow plate hole

While raising my mast, I noticed the forestay extender strands were frayed.    I got a new heavy duty forestay extender but the top "screw-in" portion of the turnbuckle will not fit down through the hole in the bow eye plate.    Should I just drill the hole out a bit or could that introduce other problems?      

I spoke to Flying Scot this morning --- used a drill to just slightly enlarge the hole and its fine.
