Fixing broken/missing screw bosses on plastic parts

Couldent you make studs out of stainless steel machine screws. Maybe 10/32 thread, and glue them into the lens with JB weld making sure they go down inside the holes for the old screws. This would eliminate the problem of self tapping screws into brittle old plastic. Then you just use nuts and lock washers on the lightbulb reflector housing side. Granted its not OEM looking, but will eliminate the problem.

I have a nice used set of factory 67 cuda taillenses with the same problem. I am gonna stud n nut em w stainless studs and JB weld.
