[DeTomaso] Headlight Bucket Shake?

[Dave McManus]

Saturday I took the Pantera out & returned after dark. I noticed the right
headlight bucket shook. It never did this before. Interstate signs showed
the vibration as the light hit the signs.

In the garage I noticed the left bucket is solid & tight and  right bucket
has about 1/4" vertical play, maybe less than 1/4". I looked in the archives
& did not find anything.

Thanks
