Dobro Truss Rod Adjustment Tool?

Dan, do You Know of a Dobro Truss Rod Adjust Tool?

Not a Les Paul question, but since Gibson owns Dobro now, maybe I can get away with it! (As you see below, at least one other person has the same queston.)
I have a 1992 OMI Hula Blues wood body Dobro that needs a truss rod tweak. I removed the truss rod cover to tighten the nut, and found that the cavity is too small to allow the use of a nut driver (like you'd use to adjust a Gibson or Guild truss rod). The cavity also is too narrow to use a standard two-ended wrench. What tool am I looking for to adjust the nut? Thank you for your response!

I have the same problem. Does anyone know what size that nut is? Man, that's a tight space.

So I have a few of the OMI era Dobro guitars. All you need is a 1/4-inch combination wrench. The closed end will just fit around the truss rod adjustment prong. So you may already have this in your toolbox, but it is small, and you may need to buy a chepo set on Amazon.
