Metric or Imperial. Or both. Depends on what they had lying around. Could be M8 but might be 3/8" UNC as they're near-identical at a glance... but not interchangeable.

many of them seem to be M8s but the headlight pods for instance seem to be a tight fit whem trying to use an M8.

Pretty sure they're a UNC in that appplication: the bonded-in inserts were probably a box of 10000 that they got for pennies and that lasted years... they should be lock-wired as well; the inserts in the pod are usually also threaded so you find that over time the bolts wind themselves out and the pods go a bit wonky. You should find the bolt heads are cross-drilled and there'll be a small hole drilled in the adjacent GRP for you to thread some soft iron or similar wire through. Twin-and-earth copper mains cable works well enough
