I think there is something about having 0's as O's too.. Like if someone had STOOPID, you couldn't get ST00PID with 0's instead.. get me..

otherwise, its 7 letters/numbers/space on aluminum or 9 on polycarb

and yeah, nothing offensive, even spelt backwards so it says something rude in the rear vision mirror of the car infront...

And as for your plate combo, I have no idea what that means... prob something to do with FHI maybe?
