240 sedan boot spring struts - removal
In the category of you learn something new every day, here’s how the spring struts on the 240 sedan (and presumably 140 sedans?) is held in place. Note there is no need to remove any pins - the spring strut is held in place by pre-load against the hinge and body bracket. The hinge is slotted and a pin on the strut slides into the slot. On the body there’s a bracket with a pin and the aluminium end piece on the strut has a corresponding notch that fits over the pin. I removed these by removing the hinges and the struts just fall out basically. Presumably you could remove them by opening the boot lid fully then compressing the strut slightly to disengage it from the slot in the hinge or body.
