Headlight bucket and signal installation

I’m trying to reinstall the front turn signals and headlight bucket on a 77 1000. There is the rubber bushing that goes into the left and right ears and the grounding washer that goes inside the bucket that fits over the signal stem. The nut then goes on to tighten the whole thing. I can’t seem to get the bucket tight enough to hold in one spot. Am I missing something here?

thats normal,they make a bottem mount but ive never seen one in captivity!

Makes for easy headlight aiming.
