I have a 1992 firebird and the top screw hole on both cup holders has broken off on the back side of the holders. So basically the top screws on both have nothing to hold onto. Any suggestions on how to fix it? Or if any for sale tell me, I need the tan ones

 

Try a good 30-minute or longer epoxy... JBWeld for example. The longer it takes to set, generally the stronger the resulting joint will be.

 

I tried quicksteel, smelss and it cracked

 

I have had luck melting them together with a soldering iron.
dont breath the fumes

 

Jb weld works great. But make sure not to torque screws down too much. even when set up completely I've cracked it and had to start all over

 

I used crazy glue and it popped right off

Second attempt with 2 part plastic epoxy building it up layer after layer. Still holding strong 3 years and many big feet later
