Thanks Jim! The pictures give good detail to work with.
I can see now how the mounting works with the two small braces supporting the bracket out in front of the dash. It was driving me crazy before thinking the main bracket bolted directly to the dash but there just wasen't enough clearance for the radar unit itself.
This configuration will do nicely and with the outboard short support bracket longer than the other the unit will have a slight canter toward the driver.
