I was wondering before I try this... I have a headlight from a JDM legacy and one of the fingers on the plastic part that pushes over a ball socket broke use to age and me test fitting a projector..

 

long story short if I don't level it, the light will shoot high.. and since I can't find a socket to fit over the ball the closest size I could find was 1/2" so I was thinking about filling the inside with ultra grey and letting it set.. It says it's flexible but by how much?

 

It's just a pivot point

I am thinking that ultra grey will be too flexible, and not work. Think about using JB Weld. Adjust to the height you want, before JB totally sets up and dries to be rock hard.

Thought about JB wield as well heh well I will have to do some testing.

JB weld is great, but the housings are made of a special plastic that JB tends not to bond too. There is a special epoxy for this carried by most auto parts stores. Can't remember the name though.

I've got this two part epoxy but I used it to mount my LED's to where the turn signal bulbs go and it's not flexible at all
