It depends upon the speedo used.
Some use reed relay sensors which pick up a signal from magnets mounted on a rotating surface (e.g. propshaft), other speedos use a variable reluctant
sensor which picks a signal from being near a spinning bit of metal (some people use diff bolts, some people (like me) make up a trigger wheel
specifically.... The advantage of the magnet based system is the gap between the sensor and the magnet can be bigger than with a VR sensor which
typically can only handle a 0.5-1.5mm gap.

Some gearboxes have built-in sensors (MT75 for example) so it is worth checking.

When thinking outside the box doesn't work any more, it's time to build a new box
