Sorry, left that out. Mine is on a Dana 30. Wonder if it's the same across all of them?
The screw has a head that fits into the a pocket in the outer knob/handle. the other end of the screw is threadless for maybe 1/8+ inch, that rides in a groove cut in the body of the hub.
I thought about getting something close and filing the threads down, but the head was too big....guess I could file that down, too.
