I know this should be in Tech, but there is MUCH more traffic here.

I started installing my coilovers this morning and when it came time to remove the strut mounts from the stock suspension, I cannot get that nut to budge. I completely twisted my 6mm allen trying to get it off. Seems when my mechanic replaced those struts mounts, he used air to get put the nut on there. Either way, I can't get it off and I need some assistance with it. I have a second car available so I can drive to you or a shop that any one can recommend that will help me...

I have a good impact gun but no compressor, Mark (AZminiman) has a good impact gun and compressor but I'm not sure if he's available this morning.

I have a good compressor and air gun here. unfortunately i will only be around for another hour or so.

Thanks for the immediate responses! Victor at Works Garage saved the day!
