I bought a 5/16" x100' warn winch line for the PTO winch on my fj40; catalog states it was supposed to come with a loop thimble, but there wasn't any in the box or attached to it. Do I REALLY need it,,,or should I just call WARN and order a replacement. All the other 5/16" thimble's I've found in the local stores seem a little small for the size of this loop. Thanks.
