Who do I have to kill to get a 7mm allen wrench. I've been to several Autozones and no one makes a 7mm. The sets switch from 5mm to 6mm to 8mm completely skipping 7mm. I understand that it might not be used often but they could at least give you one when you buy a pack of 9 or 13. I need to get one tonite so I can finish changing my pads and go to work tommorow. Any help would be appriciated.
