Thanks BTD
I ended up using around 40 points to develope the shape. I picked around 65 or so but I used a lot of them as double check points just to verify my geometry.
There were also 9 points in space to locate the mounting bosses but those are inconsequential for shape developement.
Here are a few pics of the 3D model. It is around 95% right now. I am still going through fitment checks for mating parts but any changes now will be very minor.

Here is a view of a couple of mounting bosses. These are on the top and are covered by that little close-out shelf so I had to develope them a bit differently then the others so they are easy to machine.
