How do you glue these back on?
I have yet to remove one of these that did not have at least one broken lug. I use west system epoxy with adhesive filler to repair them. I also reinforce others before they break. The pieces and surrounding area needs to be scuffed well for adhesion. Also dont build up too thick or you may have problems fitting back into the holes on the glove box. You could enlarge the holes in the glove box door if needed but I have not had to do that yet.
JB weld will work but I prefer to use the west system with adhesive filler because I can thicken it to where I want it. JB tends to be a little too fluid for repairs like this.
