Classic Mustang Restoration Guide

"All the resources you need for your restoration project, from start to finish."

Last Updated September 29, 2025 | Meghan Drummond

It's not an overstatement to say that the Mustang's debut in April 1964 changed the car scene in America. Since then, the Mustang has been in continuous production for more than five decades. Though the modern generations have horsepower and torque that would have blown Carroll Shelby's socks off in the '60s, there's something about the first-generation Mustang that's stood the test of time.

The father of the Mustang, Lee Iacocca, wasn't trying to start a revolution. What he and the Fairlane committee tried to do was create a car that was light and inexpensive with a short wheelbase for sporty handling. It needed to be under 2,500 pounds and under $2,500, with enough options that everyone could see themselves in it.

The 1965 Mustang hardtop would have an MSRP of $2,427, and at its lightest configuration, weighed 2,562 pounds. When it was first shown at the World's Fair in New York, the response was overwhelmingly positive. The 1964.5 and 1965 models together sold roughly 686,000 units. Its immediate success has helped contribute to the Mustang's lasting legacy. There were so many first-generation Mustangs that it's not hard to find survivors today.

That's only one of the reasons first-gen Mustangs are so popular for restoration. The Mustang managed to look unique, bypassing any sort of generic styling. The simple body lines have stood the test of time, and the performance is still jaw dropping. The Mustang is an excellent blank canvas for many enthusiasts to build their dream car.

Restoring a classic Mustang is an item on bucket lists of both individuals and family members who plan to restore America's favorite pony car together. Though restoring any classic car requires time and hard work, that's part of the appeal.

There's a sense of pride that comes from working hard to make something better than it was before. Driving a car whose every nut and bolt you've touched generates a sense of accomplishment and satisfaction that is immeasurable.

Though every restoration project is a little bit different, there are a few steps they share. That’s where this guide can help. We can tell you what your Mustang came stock with, what options were available at the time, how to change out different components on the car, and how to perform minor sheet metal repair.

Projects like completely rebuilding an engine, correcting a bent frame, or creating a classic Mustang that’s entirely electric require other source materials. Where possible, we’ve tried to add some guidance, tips, and links to the sources we’ve found helpful. In general, you should expect there to be extensive research for your restoration project. Though we’ve done our best to make sure that all the information here is accurate, well-sourced, and not misleading, no one source is perfect.

We hope this guide helps you start your restoration project on the right foot, and that you’ll be more excited with each page.
