1966 Ford Mustang Parts

It's impossible to deny the appeal of a 1966 Mustang. Decades later, it's still the bestselling year ever. Whether you have a '66 that's been lovingly maintained or one that's seen better days, we've got the parts you'll need to get your Mustang road-worthy or show-ready.

Keeping your Mustang true to its factory specs requires dedication and regular maintenance. It's a lot easier with the right replacement parts though. As fellow classic Mustang enthusiasts, we've worked hard to make sure we have parts that look, fit, and function just like your originals. Since these parts are made to spec, they're a direct swap-in for the original part.

For 1966 Mustangs that are going to be driven frequently, it's worthwhile to consider going modern in some key areas. Modern brakes and lighting are two areas where you'll notice a major improvement with newer parts. Restomod parts make it possible to enjoy these modern amenities while preserving the look and feel of your Mustang.

Whether you're looking to replace a single part or trying to do a total overhaul, we offer options to help you get your 1966 back up and running so you can spend more time behind the wheel.
