Short of new ones, I have seen a add on to super glue in the form of a white or black powder that you pour into place and then drip in the super glue.
Bought some at auto show, and man o man, I used it to rebuild the plastic window frame of a camper door.
Unbelievably strong.
If they sell it, buy the accelerator too. Goes down first and preps the surface for max hold.
I have it at my office, or I would post their website.
