[Collins] 30S-1 panel nut info needed

[J Allen Call]

On the back of the 30S-1 panel there are three nuts that hold the ON
 switch, the Indicator switch, and the OFF switch to the panel.  Does 
anyone know a source for these nuts or better still does anyone have 
some available? I need three but will settle for any amount.  I have 
checked all of the sources that I can think of but no luck. Thanks for 
looking.
