What's the biting point like?  If that's fine then leave it alone.

I don't know the MGA master but on the MGB the master piston comes back 
to the circlip in the bore and positions the resting position of the 
pedal, and that determines how much 'throw' you have at the pedal, the 
slave cylinder and hence the release bearing.  Slop in the linkage at 
the pedal puts it closer to the floor and results in less slave piston 
movement and hence a lower biting point.  The same is not true of the 
linkage at the clutch end as a spring inside the slave cylinder pushes 
the piston out to take up all the play at that end, and more importantly 
to compensate for the graphite release bearing wearing down.  The more 
that wears the further the piston moves out, drawing fluid down from the 
master reservoir, so you continue to get a full stroke of the release 
arm.  That makes the MGB clutch system self-adjusting, and there is no 
scope for threaded adjustment anywhere in the system.  But as I say that 
is the MGB not the MGA.
