I saw a related thread. So please don't refer me to it.

I have a headlamp that needs replacement. I found one on ebay that has a broken tab. The long tab.

How can I take what I need from both and make a non broken assembly?

OR how can I fix the tab without taking it to a service shop?

 

Ok, let me make this even more specific. How can I fix or replace the top tab? The long one on top. I hear it can be done. It can't be that difficult. I just don't have the light in front of me to examine. I work all day.
