Could anyone please assist. I need evidence that the 911S(T) was built and ideally homologated for competition before the end of 1971. I cannot find sufficient detail in the myriad of books I have on Porsche/RSR.
Also, that documentary evidence that the 1971 (however late) car ran with the 2.5 litre motor. I must stress I need FIA or Porsche documents.
Can anyone provide me with a digital version of such documents? Any help would be very much appreciated.
