Can you fix a broken plastic headlight mounting tab?

Buying a whole new headlight assembly is expensive, but relying on temporary fixes like JB Weld or bolts without the mounting tab creates uncertainty about whether the part will hold up on the road. Without proper tools and space at hand, drivers are left trying to figure out if a quick fix will last long enough to get them to a store for a proper bracket replacement.

I was replacing the alternator and I was trying to push back the little bushing that holds the alternator tightly in place, but the whole tab snapped off.source ↗

will the bolts hold it in place without the tab? will this make it to work tomorrow? I have jb weld at my work and more tools. will jb weld hold it?source ↗

You think it will make it the 20-30 miles it would take to go get a bracket and bring it to my work where there’s tools and whatnot? I’d ideally like to replace the bracket but the truck is outside my girlfriends house where I don’t have my tools or space to work on it.source ↗
