Base Alignment on Irregular Shaped Parts

[[Da...]]

Can someone give me an idea of how to fixture and base align this part? I am used to doing parts with flat planes perpendicular to each other that I can use for the alignment, but this part does not have that. 

I was thinking I would lift the part on standoffs although I am not sure how I will square it up or keep it from spinning (side note, if anyone has a recommendation for fixturing items that you find versatile or game-changing, feel free to pass those along!) Then I was thinking I would combine the tops of the two "wings" into a single plane and use that as Z origin. But as far as X and Y origins, there are not any planes perpendicular to those that I could use. I thought about making a plane on the back side of the tail and another on the top ledge of the tail and creating an intersection line and using that as the X origin, but I that still leaves Y and clocking. 

I am just completely stuck right now, so any input you have will probably generate a bunch of follow up questions from me, but I would appreciate any direction you can give.

Just a quick stab in the dark.

I would create my Base Alignment on the side plane with the 3 holes in it, using the plane as spatial/origin (3 DOF), the 2 holes for clocking/ vertical origin (2 DOF). and the symmetry of the 2 holes as the horizontal origin(1 DOF) to center to the part/model. From there you can start to establish other alignments/features to meet your print requirements and/or create more robust alignments that consider datums, etc.

Would I need to do anything special to account for the fact that the side plane would not be perpendicular to the table?

Wow thank you! What program did you use to make those illustrations? I am sure the cost wouldn't be approved any time soon for me to be able to get it, but it sure looks swell!
