While there is a slight chance of it being something that can be adjusted, if it has not been fiddled with (particularly the clutch master cylinder pushrod and pedal position), there are two possible causes apart from this. This clutch is self-adjusting via the hydraulics
1. Clutch plate is worn. Simply due to age and use (or misuse). Using the clutch pedal as a footrest will wear the clutch plate.
2. Clutch plate has oil on it. This can come from the gearbox, usually a result of overfilling, or from the engine, usually a result of failure of the rear crankshaft seal or excess crankcase pressure due to blocked crankcase ventilation. In either case, the oil usually does not get onto the clutch unless the flywheel housing drain is blocked.
Regardless, the engine/gearbox will need to be separated, meaning that one or the other must be removed, although it is (just) possible to move the gearbox back enough to replace the clutch without actually removing the box. Since the crossmember under the box is not removable, removing the box means removing a cab/hardtop, seatbox and floor. Depending on available equipment and the body, removing the engine may be easier.
Note that there are two different clutches fitted - 9" and 91/2". These can be interchanged complete, but the driven plate and pressure plate (also called clutch cover) are not interchangeable, and you also need a spacer on the slave cylinder. The only way to tell which you have is have a look - if you remove the gearlever and its mount you can see which is fitted. Note that the clutches are not the same as Series 3, although the 91/2" driven plate is the same as the Series 3.
It is generally considered that you should replace the driven plate, pressure plate, and pilot bush in the flywheel. This is based on the labour cost of removing the engine or gearbox. It is possible that the flywheel may need machining, but if it has not been abused, in my experience this is unlikely. Similarly, in my experience replacing the pressure plate is also usually a bit of overkill.
The throwout bearing on Series 1,2,and most 2a* is inside the gearbox and will not need replacing, and will not be included in a "clutch kit".
If the crankshaft seal is leaking, this is not an easy fix - one of the worst jobs on the car!
*Home market very late model 2a station wagons had an all synchro gearbox that is not the same as the Series 3 box,but is similar layout. There are very few if any of these in Australia.
