Recently I was watching "Monster Garage". The challenge on this
episode (37) was for the team to build a very fast car out of a jet
boat. During the build one of the team members spent six dollars and
some change for an expired helicopter piece. Since the part had been
expired it was apparently only worth a little over six dollars as
scrap aluminum. My question is, what piece of the helicopter is this?
Where did he get it? Or rather where can someone buy expired
helicopter parts?

Basically I live in central California, and since i've been interested
in aviation practically my whole life, i would like to get my hands on
one or more of these parts if they can be found for a reasonable
price.

Thanks to anyone offering advice on where I can find these helicopter
parts.
