For many enthusiasts, restoring an early Holden starts with the bodywork or engine bay. However, it is the interior that ultimately determines how enjoyable the car is to own and drive. Whether you’re behind the wheel of a 48-215, FJ, FE, FC, FB, EK, EJ, EH, HD or HR Holden, the cabin is where you spend all of your time, and after 50 to 75 years, most interiors are showing their age.
Sun exposure, moisture, daily use and decades of repairs can leave original interiors faded, cracked, sagging and worn out. Fortunately, the simplicity of early Holden interiors makes them relatively straightforward to restore compared to many modern vehicles. With the right approach and quality products, it is possible to return even a tired cabin to near-factory condition.
Assessing the Interior Before Starting
Before ordering parts or pulling the interior apart, spend time assessing the condition of the cabin.
Pay particular attention to:
- Seats
- Door trims
- Headlining
- Carpet
- Dash components
- Steering wheel
- Window winders
- Door handles
- Rubber seals
Take photographs before disassembly. This can save countless hours during reassembly.
Many restorers are surprised by how many small components need replacing once the interior starts coming apart.
Seat Restoration
Seats are often the most visibly worn component inside an early Holden.
Common Problems
- Torn vinyl
- Split stitching
- Collapsed padding
- Broken seat springs
- Sun damage
The condition of the seat frames should be assessed before investing in new upholstery.
Original Vinyl vs Modern Materials
Most early Holdens used vinyl trim rather than cloth.
Today’s reproduction materials often offer:
- Improved durability
- Better UV resistance
- Easier cleaning
- More consistent colouring
For concours restorations, factory-style reproduction vinyl remains the preferred choice.
For drivers, modern materials may provide a longer-lasting solution.

An interior restoration is one of the most rewarding projects you can undertake on an early Holden. While engine upgrades and paintwork often attract the attention, it is the cabin that ultimately determines how enjoyable the car feels every time you get behind the wheel.
