    Actually, it looks like it has come off from here. Reversing sensor?

    So what is the little tower bit in the first picture?

    Yep that's the reversal sensor/contact. It came off on my GB too, but it can be mounted back quite easily. I measured with the voltmeter and it still works :)

    Yes, got to the bottom of it. It is indeed the speedo connection. I need to use a mk2 1.3 cable to connect it to the cluster. I’m pretty sure this is already what we have with the box we have on the car (I forget what box it is connected to the AGG).

    I am very curious about why the slave cylinder is mounted on the diff, as far from the clutch as possible. Or is it just (external) mounting?
