Repair arm rests mounting tab...possible?

On my 66 dart sedan, I am trying to refresh the old arm rests. As I take the off, I now see that several of the mounting holes in the arm rests is cracked/broken. Is there any sort of may to strengthen those 2 plastic tabs that the screws go through to the panel? Seems sorta cheap design, as one strong pull/push of the door using the armrest will break the mount. So old and brittle. Just wondering if anyone has figured out something to strengthen that point. Epoxy? washer sandwich??

This works wonders. check all the videos, especially the last one.
