Introduction

Converting a 1968 Mustang from a coupe to a fastback is a dream project for many classic car enthusiasts. Not only does it enhance the car’s sporty aesthetic, but it also allows for a unique build that stands out at car shows and meets. This post aims to provide a step-by-step guide on how to approach the conversion process, including tips, tricks, and product recommendations.

Understanding the Differences

Before diving into the conversion, it’s essential to understand the differences between a coupe and a fastback:

  • Roofline: The fastback features a sleek, sloping roof compared to the coupe’s more traditional design.
  • Trunk Space: The fastback’s design also impacts the trunk space significantly, so consider how that will affect functionality.

Tools and Materials Needed

Before starting your project, gather the necessary tools and materials:

  • Basic tools: wrenches, screwdrivers, jack stands, etc.
  • Replacement parts: fastback roof skin, rear quarter panels, and any additional hardware specific to your conversion.
  • Conversion kits: It’s worth researching products that provide essential parts specifically designed for this conversion. Brands often have good options available.

Step-by-Step Guide

  1. Planning and Preparation:

    • Before you begin, check your local regulations regarding vehicle modifications.
    • Make sure your workspace is well-equipped and organized.

  2. Remove the Coupe Roof:

    • Start by carefully removing the coupe’s roof. Ensure you have a buddy to help, as this can be heavy and cumbersome.
    • Be cautious of any wiring or glass that may need to be removed first.

  3. Install the Fastback Roof Skin:

    • Fit the fastback roof skin onto your Mustang, making sure it aligns properly with the existing body structure.
    • Secure it in place and make any necessary adjustments.

  4. Modify the Rear Quarters:

    • Depending on the kit you choose, you might need to alter the rear quarter panels to fit the fastback design correctly.

  5. Finish the Edges:

    • After securing the roof and quarters, tidy up the edges and seams with welding or body filler as needed.

  6. Final Touches:

    • Once the structural changes are completed, it’s time to paint and finish the car to match your style preferences.

The conversion process can be intricate, and it’s essential to document everything as you go, not only for your reference but for others who may follow your lead. Don’t hesitate to ask questions or share your experiences with the community—there’s a wealth of knowledge among Mustang enthusiasts. Happy building!

Converting a 1968 Mustang coupe to a fastback is an exciting project! Make sure you have the essential tools like a wrench set, screwdriver set, and a quality jack. You’ll also need replacement fastback parts and a welder for custom modifications.

Agreed! The transformation is so iconic. What modification areas should we focus on first?

A good checklist is vital! Start by assessing the roofline alterations and rear quarter panels. Don’t forget to check for proper alignment to ensure a seamless fit between new and old parts.

Absolutely! Besides the roofline, don’t forget to account for the rear glass. Are there specific suppliers for fastback parts you recommend?

Regarding suppliers, check out MustangsUnlimited and CJ Pony Parts. They have great fastback conversion kits specifically designed for 1968 models!

Thanks for that! Is there anything special I should know about installing the fastback roof?

When installing the fastback roof, ensure you have a solid weather stripping and proper sealing to avoid leaks. Also, take your time to fit it correctly before welding!

Great tip! How about interior modifications? Will we need to adjust the rear seats significantly?

Yes, the rear seats will likely need to be custom-fitted. It’s a good idea to look at aftermarket seats designed for fastbacks if you want a snug fit.

Custom work? Sounds like a fun challenge! Are there any specific tools you found indispensable?

I’d say a good angle grinder is a must! It helps with cutting and refining fitment. And you can never have enough clamps for holding pieces in place while you work!

When painting, it’s crucial to mix your paint in small batches to match the color perfectly. Test it on a small surface first to ensure your shade is exactly what you’re after.

I’ve always loved the fastback style! The first step is to carefully cut off the coupe roof while keeping the body integrity in mind. Make sure to use a quality saw to avoid any metal tearing.

That’s a great tip, johndunn! What tools would you recommend for the cutting process?

You’ll need a reciprocating saw and some metal snips for the finer edges. Also, don’t forget safety gear—this can get messy!

Thanks for that, ocuevas! What about structural reinforcements once the roof is off? I want to keep it safe.
