Help wanted please (pictures, drawing)

D=7-1/16"
Overall Length is 29-3/8" Length to the angle is 28"

The panel face is bowed out starting about 1/2" in front of the "D" hole. That is where the 7-9/16 comes from measuring over the bow. From the "D" hole back it is basically flat. Should see in the color picture. Looks like they get resized when uploaded.
