Anthony, what CAD program did you use? :)
On a serious note I see what you mean now but my initial question still stands .
In order to mill bosses B & C to provide a reference for the fixture you need to be sure that you are at 90 degrees to the axis of the pin. You need to get that right so that you end up with my "Yes Please" rather than my "No Thanks". The centreline of the pin is the key.
Like I said, you have to establish that before you can machine the bosses.
