lens and mirror separale? W124 US headlight
 

Are they glued together? Or can we separate them and put them together?

My left headlight lamp has crack and hole. It seems the cracked debris are inside the headlight.

Due to the shape of the hole, I think I need to apply headlight repair epoxy from the inside. It looks like a horn facing into the bulb.

Because they sell only headlight insert (lens and mirror body), not headlight lens separately, and because there are only two metal clips between the lens and mirror body, I think they might have been glued together.
