I just picked a rock had rally bash plate for my 640 off one of the aussie inmates.
What a brilliant peice of kit.
Just wondering if you have considered another method of securing the lids I will probably change them to wings nuts for ease of access. seems a bit odd to me that you need to carry an 8mm to get into your tools in the tool box.
Perhaps some zeuss fasterners would work as well.
I know it comprimise security but it would be much easier.
