2008 honda civic ex battery tray andtie down?

I have a 8th gen Honda civic ex, 2008 to be precise. I'm wondering if anyone has the dimensions for the battery tray and the tie down strap. If you have the dimensions for the bars that connect the two together that would be great
thanks

Added (1). I'm going to be making my own tray, tie down bracket, and posts. I don't need the parts, just dimensions.

Whatever you need are in the diagram in the following link: All OEM parts at a whole sale price for your exact 2008 Civic EX:
