Alright, this might sound kinda stupid, but I need to ask it just to make sure.

Is there any real difference between gear sets for a Version 7 mechbox and Version 2 or 3? I want to find out because I already have a torque up gear set like I want for my M14, but it's for a version 3 mech box, not a version 7. So I need to know if I can still use them in it and save myself some money.

Thanks.
