[Amps] Help with Henry Amp mechanical challenge

[Radio WC6W]

Hi Mike,
   That's a star wrench from ancient times.

    Beware!  An internet search will likely bring up Torx (6 spline wrenches) rather than the true 4 point star.

 Greetings,
 
  
 
     I am repairing a Henry
 1KD5 for a friend.  It was a 80-15m model that
 was upgraded to 80-10m and no longer
 worked on 40-20m.  I found that the cam
 shaft switches used for fixed tank C
 were not band aligned with the
 bandswitch leaving padder caps in place
 on 40/20m.
 
  
 
     Simple to fix
 right?   My problem is I went to loosen the shaft
 coupler
 and looked for the allen screws. 
 Difficult for me to see but with some
 visual aids I see that this amp has
 what looks like a phillips spline type
 screw.  Approximately 2mm or
 0.079" inside the shaft fit, but it appears to
 be a X shaft spline.  What is the
 proper name for this screw and tool that
 would be used to remove it?  
 
  
 
     Also there are 4 screws,
 2 each on 90 degree offsets.  Two I can get to,
 and the other 2 are accessible maybe
 with right angle tool, like an allen
 wrench was made to do.   Any hints
 on access or maybe swap the couple out
 completely for one that uses standard
 hardware.
 
  
 
     Many thanks in advance
 from the not mechanically inclined.
