[R-390] Need a MC knob clamp and BFO extension shaft clamp

[stoth47 at yahoo.com]

I need a replacement bristol screw clamp for the megacycle knob on one of my R390A's - the existing one will not hold firm on the shaft no matter how much it is tightened down and the knob keeps slipping.  
 
I also need a bristol screw clamp for the BFO front panel extension shaft.
 
Anybody have any spare hardware that is available?   You can hit me off list.  
 
Also, where can we get spare bristol screws for the clamps?  I checked McMaster Carr for both bristol and six spline set screws and couldn't find them.  Maybe I'm searching on the wrong description?
 
Thanks!
