Original vintage Porsche factory repair manual supplement for the 1977 Porsche 911 USA model.
Marked “Supplement to Repair Manual 911 (XXXV – USA).” Contents include 1977 model modifications, CIS testing and adjustment specifications, injector testing, mixture-control-unit updates, clutch spring adjustments, exterior mirror installation and automatic speed-control troubleshooting.
This is a genuine older workshop manual supplement—not a modern reproduction. It is in used shop condition with age-related discoloration, stains, surface marks, edge wear, handwritten notes and wear around the binder holes. Please examine the photographs carefully for the exact condition.
The pages have not been individually inventoried, so completeness is not guaranteed. Sold as pictured and as-is.
A useful original reference for a Porsche 911 owner, restorer, collector or independent Porsche repair shop.
