The metal insert you are talking about sounds like the Rivnut or 
"Rivet Nut" that is used to replace stripped out threads in thin 
metal. We used to use them on aircraft when I was a Coast Guard 
Aviation Structural Mechanic.

I think "Rivnut" was a brand name (kind of like "Kleenex") and the 
manufacturer was either B F Goodrich or Goodyear.

I bought some rivet nuts from Aircraft Tool Supply a couple of years 
ago. It is possible they would have what you need, or if you know an 
A&P at the airport, you might be able to bum a couple of inserts and 
an installation tool.

Hope this helped out.
