Greetings Gary!
This was a project that I thought abut trying then decided to turn it over to my Airstream dealer. The two Minuets that I am aware of with rock guards on the front windows have been dealer installed/modified. I posted a few photos of the installation of the guards on my Minuet to the thread linked below:
Minuet Front Window Rock Guards
I think all of the forum members who have rock gurads on their Minuets posted information to that thread.
Good luck with your installation!
Kevin
