@IaM-Ray Thanks for mention, Ray!
On my previous VS, I used this detachable mirror to eliminate passenger-side blind spots when I had my surfboard in the car. Click on pics to enlarge.
On my currents VS, this is the detachable mirror I use when surfboard is in the car.
Both mirrors also helped eliminate passenger-side blind spots when the top is up (with or without side curtains).
Hope you find these visual references helpful.
