Hey guys! Let's dive into the world of classic cars, specifically focusing on the 1980 Buick Regal and those often-troublesome bumper fillers. If you're a proud owner of this iconic vehicle, you've likely encountered the common issue of these fillers cracking, crumbling, or simply disappearing over time. Don't worry; you're not alone! This comprehensive guide will walk you through everything you need to know about replacing your 1980 Buick Regal bumper fillers, ensuring your ride looks as good as it did back in the day.

Understanding Bumper Fillers

So, what exactly are bumper fillers? These are the body parts, typically made of a flexible material like polyurethane or rubber, that fill the gaps between the chrome bumper and the car's body. They're designed to create a seamless, aesthetically pleasing look. However, due to their material composition and location, they're constantly exposed to the elements – sun, rain, snow, and temperature fluctuations. Over time, this exposure leads to degradation, causing them to crack, warp, and eventually disintegrate. Maintaining these fillers is crucial for preserving the original look of your Regal.

Why Replace Them?

Replacing your 1980 Buick Regal bumper fillers isn't just about aesthetics; it's about maintaining the integrity of your car's design and protecting the underlying body panels. Here's why it's important:

• Aesthetics: New bumper fillers drastically improve the overall appearance of your Regal, restoring its original showroom shine.
• Protection: Fillers help protect the body from road debris, moisture, and other potential damage.
• Value: A well-maintained classic car is worth more than one with visible damage or missing parts. Replacing the bumper fillers can increase the resale value of your Regal.
• Prevent Further Damage: Cracks and gaps can allow moisture and debris to accumulate, leading to rust and corrosion on the surrounding metal body panels. Replacing the fillers prevents this damage from occurring. Regular inspection can help you identify problems early.

Finding the Right Replacement Fillers

Okay, so you're convinced you need to replace your bumper fillers. The next step is finding the right ones. Here's what to consider:

Material

• Original Material: Originally, these fillers were made from a semi-rigid plastic. Replacements often come in similar materials but with improved UV resistance and durability.
• Urethane: Many aftermarket fillers are made from urethane. This material is more flexible and resistant to cracking than the original plastic, but it may require more preparation and care during installation.
• Fiberglass: While less common, fiberglass fillers are also available. These are typically more rigid and may require more modification to fit correctly. They can be a good option if you're looking for a more permanent solution, but they may not offer the same level of impact resistance as urethane.

Quality

• Aftermarket vs. OEM: You'll need to decide whether to go with aftermarket or Original Equipment Manufacturer (OEM) fillers. OEM fillers are made by the original manufacturer and are guaranteed to fit perfectly. However, they can be more expensive. Aftermarket fillers are made by third-party companies and can be a more affordable option. However, the quality and fit may vary.
• Reviews and Ratings: Before purchasing any fillers, read online reviews and ratings to get an idea of their quality and fit. Look for brands with a good reputation and positive feedback from other Regal owners. Check online forums and communities for recommendations.

Fitment

• Specific to Your Model: Make sure the fillers you purchase are specifically designed for the 1980 Buick Regal. There may be slight variations between model years, so double-check the compatibility before buying. Confirming the correct year and submodel will ensure a proper fit. Some fillers are designed to be universal, but these may require additional modifications.
• Front vs. Rear: Bumper fillers come in different sizes and shapes for the front and rear bumpers. Be sure to order the correct ones for your specific needs. Check the product description carefully to ensure you are ordering the correct parts. Some vendors offer complete kits that include both front and rear fillers.

Where to Buy

• Online Retailers: Websites like eBay, Amazon, and classic car parts suppliers offer a wide selection of 1980 Buick Regal bumper fillers. Be sure to compare prices and read reviews before making a purchase.
• Classic Car Parts Suppliers: Companies specializing in classic car parts are a great resource for finding high-quality replacement fillers. They often have knowledgeable staff who can help you choose the right parts for your car. These suppliers often carry a wider range of parts specifically designed for classic cars.
• Local Auto Parts Stores: While less likely to have them in stock, some local auto parts stores may be able to order bumper fillers for your Regal. Check with your local stores to see if they can help.

Tools and Materials You'll Need

Before you start the replacement process, gather all the necessary tools and materials. Here's a comprehensive list:

• New Bumper Fillers: Obviously, you'll need the replacement fillers themselves.
• Socket Set: You'll need a socket set to remove the bolts holding the old fillers in place. Make sure you have a variety of sizes to accommodate different bolts.
• Wrench Set: A wrench set will also be necessary for removing bolts and nuts. Again, ensure you have a variety of sizes.
• Screwdrivers: Both Phillips head and flathead screwdrivers will come in handy for removing screws and prying off old parts.
• Pliers: Pliers can be used to grip and remove stubborn fasteners or to bend metal if necessary.
• Putty Knife or Scraper: A putty knife or scraper will help you remove any old adhesive or residue from the bumper.
• Sandpaper: You'll need sandpaper to smooth the surface of the bumper before installing the new fillers. Use a medium-grit sandpaper followed by a fine-grit sandpaper.
• Primer: Primer will help the new fillers adhere to the bumper and provide a smooth surface for painting. Choose a primer specifically designed for plastic or urethane.
• Paint: You'll need paint to match the color of your car. You can find the paint code on a sticker inside the driver's side door or in the engine compartment. Consider using a clear coat to protect the paint and give it a glossy finish.
• Adhesive (if required): Some fillers may require adhesive to hold them in place. Use a high-quality automotive adhesive that is designed for plastic or urethane.
• Safety Glasses: Protect your eyes from debris and chemicals by wearing safety glasses.
• Gloves: Wear gloves to protect your hands from dirt, grease, and chemicals.
• Masking Tape: Use masking tape to protect the surrounding areas of the car from paint and primer.
• Clean Rags: Keep clean rags handy to wipe up spills and clean surfaces.

Step-by-Step Replacement Guide

Alright, let's get down to business! Here's a step-by-step guide to replacing your 1980 Buick Regal bumper fillers:

Step 1: Preparation

• Park your car on a level surface and engage the parking brake.
• Disconnect the negative battery cable to prevent any electrical accidents.
• Clean the area around the bumper fillers with soap and water.
• Mask off the surrounding areas of the car with masking tape to protect them from scratches and paint overspray.

Step 2: Removing the Old Fillers

• Locate the bolts or screws that hold the old fillers in place. These are typically located on the inside of the bumper or on the body panels adjacent to the fillers.
• Use a socket wrench or screwdriver to remove the fasteners.
• If the fillers are stuck, use a putty knife or scraper to gently pry them away from the bumper.
• Be careful not to damage the bumper or surrounding body panels.
• Once all the fasteners are removed, carefully pull the old fillers away from the bumper.

Step 3: Preparing the Surface

• Use a putty knife or scraper to remove any old adhesive or residue from the bumper.
• Sand the surface of the bumper with medium-grit sandpaper to remove any imperfections.
• Follow up with fine-grit sandpaper to smooth the surface.
• Wipe the surface clean with a tack cloth to remove any dust or debris.

Step 4: Priming and Painting (If Necessary)

• If your new fillers require painting, apply a coat of primer to the surface.
• Allow the primer to dry completely before applying the paint.
• Apply several thin coats of paint, allowing each coat to dry before applying the next.
• Follow up with a clear coat to protect the paint and give it a glossy finish.

Step 5: Installing the New Fillers

• Position the new fillers in place and align them with the mounting holes.
• If necessary, apply adhesive to the back of the fillers to help them stay in place.
• Use a socket wrench or screwdriver to install the fasteners.
• Tighten the fasteners until the fillers are securely attached to the bumper.
• Be careful not to overtighten the fasteners, as this could damage the fillers or the bumper.

Step 6: Final Touches

• Remove the masking tape from the surrounding areas of the car.
• Clean the new fillers with soap and water.
• Inspect the installation to ensure that the fillers are securely attached and properly aligned.
• Reconnect the negative battery cable.

Tips and Tricks

• Warm the Fillers: On a warm day, leave the new bumper fillers out in the sun for a few hours before installation. This will make them more flexible and easier to work with.
• Use a Heat Gun: If you're having trouble getting the fillers to conform to the shape of the bumper, use a heat gun to gently warm them. Be careful not to overheat the fillers, as this could damage them.
• Test Fit First: Before painting or permanently attaching the new fillers, test fit them to make sure they fit properly. This will help you avoid any surprises later on.
• Take Your Time: Replacing bumper fillers can be a time-consuming process, so don't rush it. Take your time and pay attention to detail to ensure a professional-looking result.

Troubleshooting

• Fillers Don't Fit: If the new fillers don't fit properly, double-check that you ordered the correct parts for your car. If you did, you may need to trim or modify the fillers to get them to fit. Be careful not to cut too much material off, as this could weaken the fillers.
• Fillers Won't Stay in Place: If the fillers won't stay in place, make sure you're using the correct adhesive. You may also need to roughen up the surface of the bumper with sandpaper to help the adhesive adhere better.
• Paint Doesn't Match: If the paint on your new fillers doesn't match the color of your car, you may need to have the paint custom-mixed. Take a sample of your car's paint to a local auto paint store and they can match it for you.
