"The Loar" truss rod wrench

Re: LM-520-VS

Anybody know of a source for a 4mm hex wrench that will fit this unit? I didn't find one on Stewmac's website, so I ended up bending a Harbor Freight wrench. It works, but I'd like one that isn't broken on one end.

Way back when I had a "The Loar" the only thing that would work properly was a ball end allen wrench. The regular did not seat well and either the wrench or socket gets damaged.
