That is good comparison.

'64 and '65 front wheel cylinders are identical across all models.
'62-'63 are of a different design, as seen in the pictures above.
And of course the super early cars use an even earlier design but visually 
similar to '62-'63.

'65 Squarebacks normally use a 20 mm master cylinder.
They also have larger rear wheel cylinders.  They are the same as Super 
Beetle fronts.
