Blinder HP-905 (Dual) placement question

[AlphaQUp]

Guys,
I am about to (read: today) pull the trigger on a new HP-905 Dual.

Here are pics of the actual car:

Could you help me with placement please?

I am ordering a Dual for now, but I don't exclude adding a 3rd sensor and mount it vertically in the front for better protection from LEO placement on overpasses.

Thank you, please let me know your thoughts.
