Factory parts manual includes all 9 sections and R/S , numbers. A reprint of the factory competion manual for the 911S and 914-6 includes special parts,options,and modifications. Lastly the very rare prelaunch service Information for the 914/914-6 models. This includes the only know factory copy of the wiring diagram I have seen for the 914-6. $1,200.

Do your homework!
