Head dampners

I finally had to replace my original feathering shaft in my V1. I already had a spare feather shaft kit. After removing my grips and feathering shaft, I examined the replacement feathering shaft parts. I was surprised to see two dampners because my V1 had NO dampners at all.

I then reviewed the video on grip replacement. It only mentioned installing one dampner, I am assuming that is correct and the second one is a spare.
