if its just the mounting ears that the bolts go thru that are broken on your old school glass headlamp, they can easily be repaired with epoxy PUTTY from the hardware store. Just superglue the ear on to hold it together while you then mold plenty of putty around the seem like modeling clay. You can't use too much. It'll be stronger than OEM after it cures.

I prefer the old glass headlamp, its classier IMO and super scratch proof.
