Bash guard measurements?

I'm looking to make a bash guard similar to the Toyota one that was an option for the Hiace.  Does anyone have the measurements or tips where it mounts?

Sorry for the late reply, but here's the skinny:

31.5" W x 14"D (not measuring the parts that curl up in front of the bumper, just front to back in the middle of the plate)

Thanks for this. I'm amazed with the crazy bends in the brackets holding it in place.

Those funky bends are from me smooshing into a snow bank while out snow wheeling. It certainly lived up to its function! Someone referred to this inevitable event as the plate "settling in"
