Porsche: Wanted: pics and specs for FLA

Hi,

I have a little Problem.
I am searching for the specs, history and pictures of the Porsche FLA.
It was a concept car/design study made of aluminium but was not a
Porsche 911.
It was shown at least at the Frankfurt IAA. I don't know the year, but
it must have been in the early 70's.

Any help/hints greatly appreciated
thanks in advance

cheers
