Ok mesured my casting and from raised bezel edge 4" tall and 13" wide. This is just front raised bezel "rectangle" not the extra flange area.
The back side side is a little awkward to measure widest point 13 3/4". Height 5 1/4" (no tabs), 5 5/8" (with tabs).
Mine is a casting from a mold that I am the 3rd owner of, but it was made from a real Volvo panel, but I am not a taking measurements off of a actual Volvo panel.
