Plastic Weld...its really simple and if you use the correct type plastic and soldiering iron with plastic tip it will last forever and it's something you can use over and over again. I've used Plastic welding for years and have tried several types of epoxies which have never lasted as long.

Just thought of this but when I replaced my heater core I broke the holes that hold the heat/ac flapper and I plastic welded it back together and installed bushings to prevent wear ont the plastic box.

plastic welding works pretty good as mentioned above.
on top of that you could do something like this

without actually buying the kit from eastwood you can do the exact same thing with regular staples and a blow torch/heat gun. hold the staple with plyers, heat it up, and press it into the plastic.
just an idea if its in a weak spot that needs some added strength
