The Complete Guide to Restoring a Classic Pontiac Interior

Pontiac: The Excitement Division

For most of its history, Pontiac was General Motors' performance brand — the division that gave us the GTO, the Firebird, and the wide-track Bonneville. Even Pontiac's more mainstream models like the Catalina, Grand Prix, and LeMans had a sporting character that set them apart from their Chevrolet and Buick siblings. Restoring a classic Pontiac means honoring that performance heritage, and that starts with getting the interior right.

This guide covers the factory shop manuals and replacement carpet you need for a proper Pontiac interior restoration.

Start With the Factory Shop Manual

Pontiac shared platforms and many components with other GM divisions, but the engineering details — engine specs, suspension tuning, wiring configurations — were often Pontiac-specific. The factory shop manual for your year is the only reliable source for these details, especially for pre-emissions-era engines and the complex electrical systems of 1970s Pontiacs.

We carry factory Pontiac shop manuals spanning four decades:

Choosing the Right Carpet for Your Pontiac

1950s Pontiacs: Bonneville and Catalina

The late 1950s were a watershed moment for Pontiac. Under chief engineer Semon "Bunkie" Knudsen, the division shed its stodgy image and introduced the wide-track stance that would define the brand for the next decade. The 1958 Bonneville and 1959 Catalina are prime examples — large, stylish, and increasingly collectible.

1970s Pontiacs: Grand Prix, Grand Am, and LeMans

The 1970s saw Pontiac navigate the transition from muscle car to personal luxury, producing some of the most distinctive American cars of the decade. The Grand Prix was Pontiac's personal luxury coupe, the Grand Am was a sport-luxury hybrid, and the LeMans was the mid-size workhorse of the lineup.

Later Pontiacs: Aztek, G5, and G6

For owners of later Pontiacs looking to refresh a worn interior, we also carry ACC replacement carpet for several models from Pontiac's final years:

What to Look for in Pontiac Replacement Carpet

  • Model-specific fitment — Bonneville, Catalina, Grand Prix, Grand Am, and LeMans all have different floor pan dimensions, even when they share a platform. Always order carpet specific to your model, not just your year.
  • Correct pile material — Pontiac used loop carpet in most of its 1950s–1970s models, with cut-pile reserved for higher-trim configurations. ACC matches the factory specification for each model and trim level.
  • Color matching — Pontiac offered a wide range of interior colors. Your trim code (on the door jamb sticker) will identify the correct color designation for your car.

Installation Tips for Pontiac Carpet

  • Use the shop manual for disassembly — Full-size 1950s Pontiacs have complex interior trim sequences. The factory manual shows the correct order for removing sill plates, kick panels, and seat hardware without breaking clips.
  • Check the floor pan — 1970s Pontiacs are prone to rust in the footwells and along the rocker panels. Inspect and repair before installing new carpet.
  • Replace the jute padding — Original padding compresses over decades. Fresh jute padding improves sound deadening and gives the carpet a factory-correct feel.
  • Warm the carpet before fitting — Molded carpet is significantly easier to work into the contours of a large Pontiac floor pan when warmed with a heat gun.
