You can still buy Hall Senders for the air-cooled engines and they're
designed to be reinstalled without removing the entire distributor.  The
Haynes manual has an extremely detailed walk-through and it involves a
couple of circlips and a pin.

Apparently, they're fairly reliable, though.  According to Peter at
VolksCafe, he sells close to twice as many ECUs and Hall Senders(if
memory serves).
