80series question

Anyone here got an 80series? Have one but don't have it in front of me at the moment. Plan on making a tool box to fit behind the rear seat between the wheel wells. Can someone get out with the tape measure and help fill in the diagram?Attachment 63818

Diagram is very rough also wanting the height of the wheel wells from the bottom of the boot, rough plan at the moment is to use the rear two screws with hooks on hem and have them inside the tool box to hold it down.

I've got one. The same project is to do on my desk. PM me I'll send you the numbers when I've measured mine
