ignition switch bezel nut

The second one from the left in top row, what is the diameter of the hole in the front of it? 13/16 or 7/8 would do me....Also the threads have to be 7/8 but I think you said everything pictured was the 7/8 thread......if that one doesn't pan out the one in the top row on the left and bottom row on the left would be my next choices.....
