Desperately needed: datasheet Countach LP 5000S

[klassiekerrally]

A friend finally managed to let his 1983 Countach 5000 S pass the German TüV tests.
To top things off, he urgently needs a copy of the technical datasheet. None of the german Lambo specialist were able -or wanted- to help. Also the factory didn't prove much helpful...
Is there anybody out there who has the datasheet of such a car, and is willing to put it on a fax to the Netherlands?

Thanks...
