Guys, can anyone tell me where i can get those hexagon key for my Ground Control. I lost the wrench somewhere and was wondering if i can pick one up from a local hardward store. I need to raise my passenger side higher, without the key i am screwed!!

Also...i find it nearly impossible to raise all 4 sides the same height. Is there a way to do it? I can't stand jacking up my car back and forth for 2 hrs just to make sure all four sides are level. any ideas? thanks

It it just a regular allen wrench that can be found in any hardware store. I'm not sure what size cause I can't find mine right now.
