Garmin Heated/Regulated Pitot

I re-purposed an extra Garmin Servo mount I had to make a mount for my Pitot tube. I installed the pitot tube according to the Garmin Installation Manual. They were very particular in the placement of the tube:
1. It had to be no further back than the 25% cord line of the wing.
2. Could be no farther forward than 2" ahead of the leading edge.
3. It had to be within +-5 degrees from the chord line of the wing.
4. It had to be within +-5 degrees of the center line of the aircraft.

The first two pics are of the bracket with a servo mounted in it for reference.
I cut the mount down in size to save weight and make it fit more snuggly in the wing. I had to drill out and file the oval hole for the pitot bracket to fit through. Once that was completed I drilled the holes for the screws to pass through.
I had to install the lock plates in the bracket before mounting it.
The bracket is held in the mount with four 8-32 screws.
