1968 Porsche 911 Parts Manual: The Complete Guide to Finding and Using Your Restoration Resource

If you are restoring or maintaining a 1968 Porsche 911, having the correct parts manual is indispensable. This guide explains what the manual contains, where to obtain it, how to use it effectively, and how to avoid common pitfalls when ordering parts. Whether you’re a seasoned mechanic or a first-time owner, this resource will help you keep your 911 authentic and roadworthy.

Why the 1968 Porsche 911 Parts Manual Matters

The 1968 model year (often referred to as the 1968 911 or 911L in the US) marked a transition for Porsche. It introduced the long-wheelbase chassis, larger brakes, and the new 901/14 engine with mechanical fuel injection on certain versions. Because many parts are unique to this year, a generic 911 manual won’t suffice. The official factory parts manual lists every component—down to the last washer—with exact part numbers, supersessions, and detailed exploded diagrams. Using the correct manual ensures you order parts that fit, avoid compatibility issues, and maintain the car’s value and originality.

What the 1968 911 Parts Manual Contains

Complete Exploded Diagrams

Each assembly—engine, transmission, suspension, electrical, body trim, interior—is drawn in an exploded view. Every numbered part corresponds to a row in the parts list. This visual reference is critical for understanding how components go together and for identifying missing or incorrect pieces.

Part Numbers and Descriptions

For each diagram, the manual provides the official factory part number, a short description (e.g., “Nut, M8x1.25, self-locking”), and the quantity used per vehicle. Many editions also include the production date range for that part, which helps when your car’s VIN falls near a change point.

Supersession Information

Original parts may have been superseded by improved or replacement versions. The manual notes these changes, often with a pointer like “use 901.xxx.xxx.xx instead.” This is vital for ordering modern equivalents or NOS (new old stock) parts that still fit.

Optional Equipment and Model Variations

The 1968 911 came in standard (911), L (luxury), and Targa versions, plus rare options like sport seats, alloy wheels, or a limited-slip differential. The parts manual covers all these variations, usually with separate sections or annotations.

Where to Find an Authentic 1968 Porsche 911 Parts Manual

Porsche Classic and Dealerships

Porsche Classic still reproduces many original manuals. Contact your local Porsche dealership’s parts department—they can order reprints or digital copies. The official part number for the 1968 911 parts manual is typically WKD 901 020 or similar (confirm with your VIN). Pricing is reasonable for a genuine factory document.

Specialized Classic Porsche Parts Suppliers

Several reputable US-based suppliers (e.g., Stoddard, Pelican Parts, Sierra Specialty) sell licensed reproductions or original manuals. These are often cheaper than the dealer and include updated fitment notes. Always verify the year coverage—some reprints cover multiple years with a supplement for 1968.

Online Downloadable Versions

PDF versions of the parts manual circulate online, sometimes from forum members or enthusiast sites. While convenient, be cautious: scans can be low quality, missing pages, or outdated. If you rely on a PDF, cross-reference part numbers with an official source before ordering.

Avoid Unlabeled Aftermarket Manuals

Some generic “repair manuals” from Haynes or Chilton contain parts lists, but they are not comprehensive enough for restoration work. They may skip obscure parts or list incorrect supersessions. Stick to the factory manual or a dedicated Porsche parts catalog.

How to Read and Use the Diagrams

Locate the Correct Group

Each major system is assigned a group number (e.g., 1 for engine, 2 for clutch, 3 for transmission, etc.). The manual’s index helps you find the right group. For example, finding a front bumper trim piece requires going to group 8 (body work) and then subgroup 23.

Identify the Part Number

On the diagram, look for the balloon or arrow pointing to the part you need. Next to it is a figure number (e.g., “Fig. 8-23”) and a reference number (e.g., “10”). Go to the corresponding parts list page, find reference 10, and note the part number.

Check for Modifications

Before ordering, look at the “Remarks” column. If it says “Use on chassis from …,” verify your car’s VIN. Also note any asterisks indicating updated versions.

Ordering the Part

With the correct factory part number, you can order from a Porsche dealership or a specialist. Provide the number exactly as written—Porsche numbers are often 10 to 14 digits with letters. If the part is NLA (no longer available), the manual may show a superseded number; use that instead.

Tips for Ordering Correct Parts for Your 1968 911

• Verify Your VIN and Build Date: Many subtle changes happened during the 1968 model run. A parts manual is only as good as the chassis data you match it against.
• Use Multiple Manuals if Possible: The factory parts manual is primary, but also consult a “parts interchange” guide from a trusted restorer to catch errors.
• Beware of Reproductions: Some aftermarket parts (rubber seals, trim) may not match originals. Always compare with the manual’s diagram and dimensions.
• Consider a Digital Copy: A PDF on your phone or tablet is convenient for the garage. Keep a printed version as backup.

Digital vs. Printed Manuals: Which Is Right for You?

• Printed (Paper): Authentic feel, easier to flip between diagrams and lists, no battery needed. Ideal for workshop use. Can be expensive but lasts forever.
• Digital (PDF): Searchable, zoomable, and portable. You can carry the entire manual on a tablet. However, screen glare and grease are drawbacks. Best as a supplement.

Most long-term restorers own both: a pristine printed copy for reference and a digital copy for daily use.

Final Recommendations

1. Obtain the official factory parts manual for 1968 Porsche 911 (part number WKD 901 020 or equivalent). If unavailable, buy a licensed reproduction from a classic Porsche supplier.
2. Cross-reference every part number with at least one other source (e.g., a reputable parts supplier’s online catalog) before spending money.
3. Join an enthusiast community like the Porsche 911 Registry or the Early 911S Registry. Members often share part number updates and can help decode manual notes.
4. Use the manual systematically when disassembling: mark diagrams with colored tabs for each system to simplify reassembly.

A 1968 Porsche 911 is a masterpiece of engineering, and the correct parts manual is your key to preserving it. Invest the time to find an authentic copy, learn to read it, and you’ll save hours of frustration and avoid costly mistakes. Whether you’re replacing a single grommet or performing a full rotisserie restoration, the manual is your most valuable tool after a good set of wrenches.
