Not sure how useful this is ... Needed to replace the rear locker actuator on my 80 and had a brand new 100 series one to hand. They're almost the same - the 100 series one has an extra bash plate stud, different breather location, and different electrical connector. Only the electrical connector difference matters. The wires and pins are the same, so I removed the electrical connector shell from the old 80 one and moved the 100 series pins into it. Bit of a fiddle to get the pins out.
