Here are the requested dimensions of the original battery box, measured from my truck that has one of these elbow-whackers.
If I can't find an original for my other truck and have to build one, I'll likely amend the dimension of the new one a bit and add an armrest pad on top.
I'll probably have it open horizontally, rather than on the diagonal.
While the manual shows the box joined with the two short ends together, the clips on my box won't work that way, and I can see no sign of them having been moved.
Cheers
