Hello. I am building my own hearth pad without the stove on site. Can anyone please give me the exact foot print measurements? Because it has angles I need the front width 1, one front side angle on right 2, one right side length 3, one front side angle on left 4, one left side length 5, one rear side angle on right 6, one rear side angle left 7, and the rear width 8. Thank you for any help.
