Metric or Imperial?

[MM77]

Assuming the car is a bare shell, (ie owning no existing parts), is there any benefit to choosing metric or imperial fittings?

 

ie, apart from where I live is there anything else I need to consider?

Even a bare shell will have some captive nuts or threaded holes in it. Gearbox crossmember is a good example, or exhaust bracket mounts maybe. It matters then.

Other than that I can't see any reason to choose one over the other. Fine threads are used in places for good reasons. They can generally be tightened more without ripping the threads out.

Do you know whether Australian shells are Metric or Imperial??

I can't see Ford changing all the threads on a model just to send it to a different country. They will all be the same. Generally Mk1 Escorts are Imperial and Mk2's are Metric. Not a strict rule for every single bolt, but not far off.
