1966 Ford Bronco Parts

1966 Ford Bronco Parts Guide

What to know before you buy parts for a first-year Bronco.

The 1966 Ford Bronco started it all, but first-year rigs can come with details that make parts shopping a little different than later Early Broncos. If you're working on a stock restoration, repairing an original truck, or sorting out years of previous owner changes, it pays to know where a '66 can catch you off guard before you start ordering parts.

Things to Know When Shopping for a 1966 Bronco

The good news is that many parts still fall under the standard 66-77 Early Bronco range. What matters is knowing when your Bronco may not match the catalog as neatly as you think. Since 1966 was the first production year, some details can be different, and many of these trucks have been repaired, upgraded, or pieced together over the decades with later components.

That means the smartest way to shop for 1966 Bronco parts is to treat your truck like an individual build. Before ordering, compare what is actually on the Bronco now instead of assuming every part is still original. This is especially true with steering, wiring, charging system parts, brake components, brackets, mounts, and trim.

Where 1966 Broncos Can Be Different

• First-year details: Some parts and hardware can vary from later Early Broncos. Some notable examples include:

  • Brakes: The 1966 Ford Bronco used a single-reservoir master cylinder. This means the brake lines, pedal assembly, center hoses, and more can vary from later years. If you are upgrading the brakes on a 1966 Bronco, you will likely need more parts to complete the conversion than you would on later models.

  • Steering Linkage: The pitman arm had a smaller tapered hole than 1967-75 Broncos. Available replacement steering linkage is generally the 67-75 style, so if you are replacing your drag link on a 1966 Bronco, you will need to make sure you update the pitman arm as well.

  • Suspension: One major suspension difference on a 1966 Ford Bronco is the rear shock mounts. The shock mounts on many 1966 Broncos were forward-facing and used a post-style upper mount. For 1967-77 Broncos, the shock mounts changed to rear-facing and used an eye-style upper mount. Some later 1966 Broncos can have the rear-facing, eye-style shocks, so be sure to check your actual vehicle before ordering.

  • Doors: The doors and door posts on a 1966-67 Bronco differed from later model years. You cannot mount a 1968 or later door on a factory 1966-67 Bronco body because the B-pillars are different and place the latch strikers in a different location. The inner door panels are also completely different from later models, so you will need panels, window cranks, door handles, and more that are specific to your Bronco's year model.

• Previous owner changes: Many 1966 Broncos now run later-model or upgraded components, which can affect fitment just as much as original year-specific differences.

• Stock vs. upgraded builds: Restoration and driver builds use different parts strategies. Decide early whether you want factory-correct parts or modern upgrades.

• Fitment assumptions: Not every 66-77 part should be installed without checking first. Pay attention to fitment notes and compare your current setup when possible.

These are just a few of the variances found in the first-year 1966 Ford Bronco. Pay attention as you shop for fitment to make sure you are getting the right parts for your build. Where applicable, we try to note year-specific fitment and whether a part can be used on a 1966 Bronco even if it is not factory-correct.

Common Mistakes First-Year Bronco Owners Make

• Ordering parts based on year alone without checking what is actually installed.

• Buying restoration parts before deciding on the direction of the build.

• Assuming major systems are still original after decades of repairs and upgrades.

• Skipping simple measurements or part comparisons before ordering.
