I have 4 cars and none have room for a box bolted into the engine compartment?Why would one do that anyway?To keep the tools warm?
It keeps the tools close to where they might be needed, locked away in a place thieves can't see or would expect to find them. Maybe it's a truck thing, there's often more room under a truck hood.
I bought a bunch of stuff at a garage sale including some large size spanner, majority in imperial sizes that are useless and I intended to forge into knives or hatchets.
Some tools sizes actually translate across. So if you have one you don't need the other. FYI5/16" = 8mm 3/4" = 19mm13/16 = 21mm7/8" = 22mmThere are others that are close, but those four really fit.
I knew some were close, but that's very interesting, thanks!
