Looking at one of my pioneer units, sitting on a shelf above my desk :
It has only 3 holes in the same place as the five you indicate (working from the left in your diagram) it has 2,3 and 4.
3. and 4. are dead centre height wise (1" or 25mm from bottom)
2. is 1 7/16" or 35mm from bottom
Now from the front it is difficult. the pioneer fits into a cage. At the front there are two small lugs which stop the cage going forward (or the stereo back)
from this the holes are:
2. 7/8" or 22.5 mm
3. 1 1/8" or 29 mm
4. 3 1/4" or 83 mm
Hope this is of some help.
*note I have another stereo (Ford) sitting around somewhere, when I find taht I will measure that too.
