What does the porsche refer to in its documents when it talks about inventory? In the document number 4. Thank you!

From what I understand from the documents, until January 18, 1972 the S / T for track could only be made in metal except for the fiber front bumper? Document 29 speaks of the CSI allowing the use of plastic in widening areas, the circular dated January 18. When he names that neither the front bonnet nor the rear can be made of plastic. Before January 18, 72. How was the hood and the rear part made? Aluminum or other metal or did it have to be metal?
Was there a difference between building a Group 3 S / T and a Group 4 S / T? In group 4, did the front bumper before this circular have to be metal? If yes, why was it?

on the track, which was the most used? Koni or bilstein? I read in the huhhg document that the bilsteins are added for the year 72 as sports equipment, that other document on the 28th is dated 7.12.1971
