Porsches With One Side Mirror: Parts Names and Identification Guide

Many classic Porsches, particularly models from the 1960s and 1970s, were originally equipped with only one side mirror—typically on the driver's side. This was a common practice in Europe and on early US imports for cost savings and aesthetic reasons. If you own or are restoring one of these Porsches, knowing the correct parts names is essential for ordering replacements or upgrades. This guide covers the specific components of a single side mirror setup, focusing on models like the 356, 911 (up to 1973), and 914.

Why Did Some Porsches Have Only One Mirror?

In the early days of Porsche production, side mirrors were optional extras. Many buyers opted for a single mirror on the driver’s side, as passenger-side mirrors were not yet required by law and were considered unnecessary. This practice continued through the early 1970s, especially on European-market cars and early US imports. The one-mirror setup reduces drag and gives the car a clean, symmetrical appearance from the driver’s perspective. It also simplifies manufacturing and keeps costs down. Even today, some purists prefer the look of a single mirror on vintage Porsches.

Identifying Your Porsche's Mirror Type

Before ordering parts, you need to identify the specific mirror style your Porsche uses. The most common types are:

• Flag mirror (1965-1973 911): A rectangular mirror mounted on a slim stalk that attaches to the door. The base is often chrome or painted.
• Teardrop mirror (356 and early 911): A rounded, aerodynamic shape attached to the front fender or door, depending on model year.
• Bullet mirror (914 and some late 356): A cylindrical mirror mounted on a short arm, usually on the door.
• Trapezoid mirror (late 1970s 911): Larger and more angular, sometimes with a black plastic housing.

Check your car’s VIN and model year to confirm the correct style. Many reproduction parts are available, but they must match the original design for proper fitment.

Parts Names for a Single Side Mirror System

A single side mirror assembly on a classic Porsche consists of several key components. Knowing the correct names helps you communicate with suppliers and avoid ordering the wrong part.

Mirror Head (Housing and Glass)

The mirror head is the visible part that contains the reflective glass. It includes:

• Mirror housing: The outer shell, usually chrome, painted, or black plastic. It may be one piece or have a separate trim ring.
• Mirror glass: The reflective surface. For single-mirror setups, it is typically flat (non-convex) to provide an accurate view. Some aftermarket options offer convex glass for a wider field of view.
• Backing plate: The plastic or metal plate that holds the glass inside the housing.
• Adjustment mechanism: Internal gears or cables that allow the driver to tilt the mirror from inside the car. On early models, this is a manual knob or lever.

Mirror Base (Pedestal)

The base attaches the mirror head to the door or fender. It may be:

• Door-mounted base: Common on 911 flag mirrors. It’s a flat or contoured plate that bolts to the door skin.
• Fender-mounted base: Found on teardrop mirrors for the 356. It attaches to the front fender with two or three screws.
• Pedestal with integrated arm: For bullet mirrors, the base includes a short arm that holds the head away from the body.

Gasket or Seal

A rubber or foam gasket sits between the mirror base and the car’s body. It prevents water infiltration, reduces vibration, and protects the paint. Gaskets are model-specific and often need replacement during restoration because they dry out and crack.

Adjustment Mechanism (Knob or Lever)

Inside the car, the driver operates the mirror via:

• Manual knob: A small plastic or metal knob that protrudes through the door panel or window frame. Turning or tilting the knob moves the mirror head.
• Lever: On some early Porsches, a short lever inside the door pulls or pushes to adjust the mirror.

The cable or rod connecting the knob to the mirror head is often called the “bowden cable” or “remote control cable.” This cable can fray or seize, making adjustment difficult.

Hardware (Screws, Nuts, Washers)

Mirror mounting hardware includes:

• Mounting screws: Usually Phillips or hex head, often with a shoulder to align the base.
• Lock washers and nuts: Used to secure the base to the door or fender.
• Finish washers: Chrome or painted washers that sit between the screw head and the base for a clean look.

Some models use a unique threaded post that passes through the door and is secured inside with a nut.

How to Order the Correct Replacement Parts

When ordering parts for your single-mirror Porsche, follow these steps:

1. Identify your mirror style and model year using reference photos from Porsche restoration guides or forums.
2. Determine the original part number if possible. Check the back of the mirror head or the base for a stamped number (e.g., 901.731.011.00 for a 911 flag mirror).
3. Choose between OEM and reproduction parts. Original equipment manufacturer (OEM) parts are rare and expensive but ensure correct fit. Quality reproductions from brands like Stoddard, Pelican Parts, or Classic Porsche are more affordable and often identical in form.
4. Match the finish. Decide whether you want chrome, body-colored, or black. Many reproduction parts come uncoated and need to be painted to match your car.
5. Check for compatibility. Some mirror bases are specific to left-hand drive (LHD) or right-hand drive (RHD). For a single-mirror car, the mirror is on the driver’s side, so order a “driver-side” part.

Practical Tips for Restoration

Restoring a single mirror setup can be straightforward if you have the right parts.

Restoring vs. Replacing

If your original mirror head is in good shape but the chrome is pitted, consider having it rechromed rather than buying a reproduction. The glass can often be replaced separately—many suppliers sell mirror glass cut to size for specific Porsche models. The adjustment mechanism can be rebuilt with a new cable kit.

Compatibility Across Models

• 356 and early 911 teardrop mirrors are similar but not identical; the base angle and mounting hole spacing differ.
• 911 flag mirrors changed slightly in 1969, 1971, and 1973. Always verify the base mounting pattern.
• 914 bullet mirrors are unique to that model; do not assume a 911 mirror will fit.

Proper Installation

When installing a new base or gasket, use a thin layer of silicone sealant on the gasket to prevent leaks. Torque the mounting screws evenly and do not overtighten, as this can crack the base or dent the door skin. For manual adjustment mirrors, test the cable travel before final assembly.

Final Recommendation

For owners of classic Porsches with a single side mirror, the key to a successful restoration is knowing the exact parts names and understanding the differences between model years. Always start by identifying your mirror style—flag, teardrop, or bullet—and then order the mirror head, base, gasket, and adjustment cable as a complete set from a reputable supplier. If budget allows, buy a kit that includes all hardware and a new gasket. Avoid mixing parts from different models unless you are prepared to modify them. With the correct components, you can restore your car’s original appearance and enjoy a clear view from the driver’s seat.
