Default Advice on Tightening an Anti-drag Wire

The bottom right wing on my S-1C has a loose anti-drag wire. It is the one closest to the fuselage. I recently purchased the plane and imagine the wire has been this way for a while

I was able to get a borescoped in the front of the wing and the block looks well attached and the washer does not appear to be cupped. My question is how should I go about retentioning the wire?

The leading edges are plywood. The wire is secured with a nut against the rib/block and a lock nut on top of the plain nut.

My idea is to drill a 1/2" or so hole in the plywood leading edge and use a socket wrench, extension, and wobble socket to tighten the nuts straight on.

Any ideas? I will post up a few pictures when I get back from the hangar.

Madman,
Most of us just put insp. rings aft of the rear spar. You probably have a dbl nut there, loosen the outer nut and add another on top of it then jam the two nuts to use to hold the wire, tighten the nut at the drag block then reverse it all.
If you do not have an insp. ring there you can cut a hole and glue a ring on the inside. Use the search function for many threads on the topic.
Sorry, just read you said "bottom wing" but you can add a plate on the bottom and do it the same way.

There is an inspection ring back by the rear wing attachment bolt, but the front of the wire is under the plywood leading edge with no access.

You do not need to hold the front nuts just untighten the nut on the clevis at the rear spar and turn the wire with a vice grip with rubber on the jaws.
