Inconsequential... you're not going to be racing on Originals. Or I should hope not.

For the record, any non-precision truck probably isn't going to be "true" 8mm.

In case you didn't get the point, your answer is 8mm. Maybe it would have been a better idea to email Original? Just putting it out there.
