    Lightbulb Replacing rear trailing arms

    Is it possible to replace the rear trailing arms on a pre 72 LWB with the gearbox in?

    Obviously the front bolts need to be cut off since they’re facing inwards but will new M14 bolt slide past the torsion tube from the outer side? Not keen on any fancy split after market bolts so will drop the drivetrain if necessary

    Regards

    I have done it by using a thinner locking nut, so the locking part grabs the shorter bolt.

    Thank you Ed!

    Just for clarification, by sticking in the bolt from the outside, hence locking nut towards the gearbox?

    Yes, that's why the bolt had to shorter.
