Oops... you dropped your gauge and now one or two of the holes won't accept factory ammo. 
 
This service is to evaluate and re-ream a few dented holes on a lightly-dropped gauge.  Contact us before buying this or sending your gauge in.  Re-reaming holes will return them to spec in areas where metal remains, but displaced metal is cut away so gauge holes may not be 100% in-spec after reaming.
