I went on my break today and I went to look for something in my 92 firebird and went I tried to open the door one side felt like it was disconnected and a little metal thing fell out of it. I can open my door but i have to do it carefully. Do I need to replace the entire door handle?

 

Yes...............
the door handles get worn and break thru time.
Any big box parts store sell the knockoff replacement handle
assembly in their "HELP" parts section.
A easy DIY fix.
