I picked up a couple esox series rods and I'm needing to replace one guide does anyone know what style guide they used. 

 

Thanks 

Brand of rod model number and or a picture will help out a lot.  Most Internet sales screens tell you most of what you need to know.

Determine what the finish is, (bright stainless steel, grey, black) size of the ring (O.D. of the ring, not the metal it's pressed or glued into), single foot or double, color of the ring, then compare its appearance to the guides you see in catalogs like Mudhole, or GetBitOutdoors, or JannsNetcraft or Pac Bay.  Buy the closest thing you can find, put it on or have it done by a rodbuilder, and you will be fine.  No need to have the exact model.  In fact in most cases the guide you are trying to find will be obsolete.  If you can match the thread color fairly well, you'll never notice if the guide doesn't quite match.
