hand brake lever mount on lower dash face.
for the height of the holes on the dash face, i just made them central to the dash panel. i.e. equally spaced between the top and bottom skins.
The lower edge height was adjusted based on projecting the line backwards from the spare tire mount. That panels plane bisects the vertical face of the dash. I did all this a couple of years ago when i was reverse engineering the chassis and did get some measurements from a number of separate people and the distances seemed to match up to within 1/4".
