Whether you're a seasoned mechanic, a weekend warrior, or just a Mustang lover looking to spruce up your ride, this guide is packed with everything you need to know. We'll explore the ins and outs of these iconic parts, from the dashboard to the seats, and everything in between. So, buckle up (pun absolutely intended!) and let's get started.

The Dashboard and Center Console

Let's kick things off with the dashboard and center console, the command center of your Mustang GT. These areas take a beating over the years, from sun damage to wear and tear from everyday use. Replacing or upgrading these parts can dramatically transform the look and feel of your interior. For the 99-04 models, finding original parts in mint condition can be a challenge, but don't worry, there are plenty of options available.

You can often find complete dashboard assemblies, including the dash pad, instrument cluster bezel, and glove box, on online marketplaces or from specialty Mustang parts suppliers. When choosing a replacement, consider the material and finish. The original dashboards were typically made of plastic, which can crack or fade over time. Upgraded options include dashboards made of higher-quality plastics or even custom-wrapped dashboards with leather or other premium materials. The instrument cluster bezel is a crucial element that holds the gauges and gives the dash its distinctive look. Replacements are readily available, allowing you to refresh the look of your gauges or even upgrade to aftermarket gauges for enhanced performance monitoring. The center console is another area where you can make significant changes. It houses the shifter, climate controls, and often includes storage compartments. Replacements range from basic, like-new consoles to custom-designed consoles with upgraded features like additional cup holders or integrated USB charging ports. Remember to pay close attention to the fit and finish of any replacement parts. Ensure they match the existing color and texture of your interior, or use this as an opportunity to change the color scheme, like swapping to a black interior or a color-matched interior. Also, check for compatibility with your car's specific options, such as the presence of a premium sound system or specific trim packages. The center console also usually has the armrest, so check the condition of it. You may change it by replacing or reupholstering it, it is a great way to add more comfort to your ride.

Seats and Upholstery

Next up, let's talk about the seats and upholstery. The seats in your Mustang GT are not only essential for comfort but also play a significant role in the overall aesthetic of the interior. Over time, the seats can show signs of wear, with torn upholstery, worn padding, or damaged seat mechanisms. If your seats are in rough shape, replacing or reupholstering them is a fantastic way to refresh the interior.

For the 99-04 models, you have a few options. You can opt for original-style replacement seats, which will maintain the factory look and feel. These are often available with various fabric or leather options. If you're looking for something more custom, consider aftermarket performance seats. These seats often feature better bolstering for improved support during spirited driving and can come in a variety of styles and materials. When choosing replacement seats, pay attention to the seat rails and mounting hardware. Ensure that the new seats are compatible with your car's existing seat tracks, so you don't run into installation issues. Another option is to reupholster your existing seats. This is a great way to save money and customize the interior to your liking. You can choose from a wide range of fabrics, leather, or synthetic materials and have the seats professionally reupholstered to match your vision. When you reupholster the seats, be sure to also check the seat foam. Over time, the foam may degrade, leading to an uncomfortable ride. Consider replacing the seat foam during the reupholstering process to restore the seats to their original comfort levels. Don't forget to inspect the seat belts and buckles. They are essential for safety, and replacements are readily available if needed. If your Mustang GT has leather seats, consider using a leather cleaner and conditioner to keep them in good condition. Regular maintenance will help prevent cracking and fading, preserving the seats' appearance for years to come. Many guys choose to add seat covers in their Mustang GT, there are many options like seat covers that look like the original seats, and others are made with different materials.

Door Panels and Trim

Moving on to the door panels and trim, this is another area where you can make a big impact on the look and feel of your interior. The door panels in your Mustang GT can suffer from various issues, including fading, warping, or damage from wear and tear. Replacing or upgrading the door panels can make a significant difference in the overall appearance of the interior.

Original-style replacement door panels are readily available for the 99-04 models. These panels will match the factory design and can be a straightforward way to refresh the interior. If you're looking for something more custom, you can explore aftermarket door panels with unique designs, materials, or features. Consider the material and finish of the door panels. Original door panels were typically made of plastic, but upgraded options can include panels made of higher-quality materials, such as vinyl or leather. You can also find door panels with carbon fiber or other performance-oriented finishes. The door trim includes various components, such as the door handles, window switches, and speaker grilles. Replacements for these parts are also available. When choosing replacement door panels, pay attention to the compatibility with your car's existing features, such as the power windows, power locks, and sound system. Also, make sure that the new door panels come with all the necessary mounting hardware, or you may need to source these separately. Remember to check the condition of the door seals. Worn or damaged door seals can let in water and noise. Replacing the door seals can improve the comfort and sound insulation of your interior. In addition, you can upgrade the door handles. There are many options, from chrome ones to black ones.

Carpets and Floor Mats

For the carpets, you have a few options. You can opt for original-style replacement carpets, which will match the factory design and color. These carpets are often made of durable materials and can withstand the rigors of daily use. Another option is to upgrade to custom-fit carpets. These carpets are designed to fit your Mustang GT's floor perfectly and often come in various colors and materials, allowing you to personalize the interior. When choosing replacement carpets, make sure to consider the sound insulation properties. Some carpets are designed with additional layers of sound-deadening material to reduce road noise and improve the overall driving experience. For the floor mats, you can choose from various options, including original-style mats, all-weather mats, and custom-designed mats. Original-style mats will match the factory design and often feature the Mustang logo.

Custom-designed mats can come in various styles and colors and often include features such as raised edges to contain spills. Remember to choose floor mats that fit your Mustang GT's floor perfectly. Incorrectly sized mats can be a safety hazard. Also, consider the cleaning requirements of the carpets and floor mats. Some materials are easier to clean than others. Many Mustang GT owners also opt for sound deadening. It can reduce the outside noise, for a quieter and more comfortable ride.

Interior Lighting and Accessories

Now, let's brighten things up with interior lighting and accessories. Interior lighting and accessories can add a touch of style and functionality to your Mustang GT. Upgrading the interior lighting can make it easier to see inside the car at night and also enhance the overall aesthetic. You can replace the factory interior lights with LED lights, which are brighter, more energy-efficient, and come in various colors. These include the dome light, map lights, and footwell lights.

Another option is to add accent lighting, such as under-dash lights or under-seat lights. These lights can create a custom look and add a touch of personality to your interior. When choosing interior lighting, consider the color temperature. Cool white LEDs provide a bright, modern look, while warm white LEDs offer a more traditional look. Regarding accessories, you can add various items to improve the functionality and appearance of your interior. These include a new shift knob, steering wheel, or gauge cluster. Shift knobs can be replaced with custom-designed ones, offering improved grip and a more stylish look.
