Read the previous posts about ensuring mount hardware was tight and putting taped weights on backside of mirrors. Had not really noticed how bad the vibes were until clocking 680 miles roundtrip Saturday Tulsa to St. Louis.
Anywho, my solution was three-fold.
1. Left side 10mm head screw was 2.5 threads longer than right side. As it was, I could see the hex head moving side-to-side even when torqued down. So added a thick stainless washer to fill the stack gap.
2. Added a 1/2" square piece of Gorilla tape to the area adjacent to locking tab since that section of the mount was the least gripped/secured quadrant.
3. Added three 0.5oz weights to the outboard side of the mirrors plastic backface, stacked vertically.
Stone cold dead.
No vibes.
