It's been many moons now, but I remember needing to completely disassemble
the entire distributor when I swapped in a Hall sender from a Volvo 740,
due to the fact that my external plastic connector was broken off, causing
intermittent running issues.  I pressed out the roll pin in the base of the
drive and pulled the whole shaft in order to remove the assembly.  Perhaps
I overcomplicated things, but that's what I did.  Near as I can tell, most
four cylinder Bosch Hall units from that era will drop right in
