is there a way to tighten up the swivel ball attachment at the Header/roof mount. under heavy acceleration it rolls up and I have to adjust it.

any ideas or tips are welcome

Try this. https://www.forabodiesonly.com/mopar/threads/loose-rear-view-mirror.86239/

all fixed. I took a socket just bigger than the cover plate dimple and gave the plate a negative crown. it might be a little to tight but i am the only one driving the car so it being tight is right.

thanks for the tip on A-Bodies.

this site rocks!!

Glad it worked.
