Cracked Headlight Attachment - Options?

Recently replaced the factory chrome grill with a knock-off TRD pro grill. Everything went smoothly until I took a step back and noticed that the left (passenger) side seemed to be lower than the driver's side so I immediately took it off and reinstalled it with no better luck. From straight ahead you can see a very small gap under the hood and upon closer inspection I found the entire passenger side to be 'hanging' slightly lower than the driver's side. I traced the issue to the headlight which has a large crack in the plastic connecting piece where it's bolted into place which is causing of the sag.

My questions are:

(1) Is there any way I can replace just the plastic housing component or would I have to purchase a new headlight?

(2) Is there any way to fix this without buying a new headlight?

(3) If it totally broke, how critical of an issue would it be? It doesn't seem like it's the only thing holding it all in place, and I wouldn't ignore it forever, just wondering if this is something I would need to fix ASAP or if a few weeks would be okay.

Below is a picture I took of the cracked plastic piece, and the 2nd pic is from a website highlighting the piece I believe is cracked.

Any suggestions or help is greatly appreciated, thank you so much in advance!

 

Not a huge issue.

Just epoxy it or drill small holes and put wire into them and cinch them down.
