Classic Mustang Door Panel Replacement

Classic Mustang Door Panel Replacement

Last Updated May 25, 2022 | Meghan Drummond

Many classic Mustang’s door panels are in serious need of replacement. Dirt, constant use, heat, age, and moisture can all cause door panels to degrade and warp. The result? Door panels that are literally peeling away from the door.

When it gets especially bad, the door panel might fall out whenever you open the door. While this isn’t as pressing an issue as damage to the engine or body, it’s still annoying. And unlike some more serious issues, installing new door panels is an easy fix.

Selecting a Replacement Door Panel

You can replace your Mustang’s door panel with a direct replacement. Or you can take the opportunity to upgrade to the Pony interior you always wanted. You can even get some restomod improvements like power door locks. Really, the sky’s the limit.

If you’re not sure what door panel your Mustang came with stock, then you can use our data plate decoder. That and our interior trim guide should help you figure out what your Mustang’s stock option was.

While adding a lot of bells and whistles can be complicated, the steps for a replacement are pretty simple.

Tip: Always pick a high-quality replacement. Some companies use cardboard backing on their panels, which can lead to warping. It can also make installation more difficult.

Before You Get Started

Each installation will be a little bit different depending on the door style. Trim locations in particular can vary.

One thing that won’t vary is the need for door panel clips. New door clips are cheap, and they’ll help you enjoy your replacement door panel for longer. If you’ve decided to install a Deluxe or Pony door panel, you’ll need deluxe door panel clips, which are longer than the standard clips.

Installing a door panel is easiest on early classics. Around ‘69, several added comfort features made installation slightly more complicated (though still easy enough for novices).

Installing a door panel for the 1965-1968 Mustangs is different than installing a panel for 1969-1970 Mustangs. Select which one is appropriate for you. If you have a 1971-1973 Mustang, you’ll basically follow the same installation process as the one for ‘69-’70 Mustangs.

Upgrade Your Whole Door Now to Save Time

It’s a good idea to consider making other installations at the same time. This is a great time to swap out door locks or window cranks that are beyond repair. But in particular, installing new weatherstripping is a good way to make the most out of your installation time.

1965-1968 Door Panel Installation

For this install, we used TMI’s Pony Interior door panels on a 1965 Mustang. Other door styles will have their trim in different places, but it will usually still be held on by the same style metal clips.

    Tools:

  • Door panel removal tool
  • 4 mm Allen key
  • Phillips head screwdriver
  • Small flathead screwdriver
  • Small Phillips head screwdriver
  • Crank removal tool (optional)

Step 1: Remove Door Panel Cup Screws

There are two screws in the door panel cup that hold the panel to the rest of the door. To remove the small pad over the screws, you can use your flathead screwdriver to lift it up. Then, simply unscrew.

Step 2: Remove Door Handle

While our door handle and window crank have a screw to hold them in place, some classic Mustangs have a crank without a screw. For these you’ll need a crank removal tool.

Step 3: Remove Window Crank

Remove the screw holding the window crank in place. Just like with the door handle, you’ll either have a screw holding this in place or you’ll need a crank removal tool.

Step 4: Remove Door Panel

Use the door panel removal tool to pop the retaining clips out. Then you’ll be able to pull out the door panel.

Pro Tip: If the stainless steel trim is in good shape, you can transfer it to your new door panel. Otherwise, you’ll also want to replace your door trim.

Step 5: Put Inner Trim onto Door Panel

Your inner metal trim is side-specific, so lay it on top of the door panel to make sure you’ve got it on the right side. Then, pop up the metal clips with a flathead screwdriver and line up the trim with the holes on the panel.

This step is time-consuming. But when properly done, it looks great and will stay in place for years.

Pro Tip: Bend down one metal clip every few holes to keep the trim in place. You can bend down the rest once you’ve gotten the clips through every hole and are sure everything lines up.

Step 6: Add Outer Trim to Door Panel

Line outer trim up with the outside edge of the door panel. Press in place as tightly as you can.

Step 7: Secure Outer Trim

Insert and tighten the screws that hold the outer trim in place.

Step 8: Add Door Clips

Take some door clips and add them to the marked spaces on the back of the door panel. Insert the door clips and then slide them forward to secure them.

Door Panel Install for 1969-1970 Mustangs

Just like with earlier first-gen Mustangs, door panel trim varies based on which packages your Mustang came equipped with. For our installation, we used a Mach 1 door panel on a 1969 Mustang. Depending on which door panel you select, you may have fewer total steps.

    Tools

  • Phillips head screwdriver
  • ¼” Ratchet
  • 9 mm Socket
  • Needle nose pliers
  • Small pick or flathead screwdriver
  • Plastic pry bar
  • Hammer
  • Punch

Step 7: Apply Decal to New Door Panel Insert

For kits like ours where the insert isn’t pre-finished, you’ll get to select which decal you apply. We selected woodgrain. Carefully apply this decal to your insert.

Step 11: Secure Metal Tabs

Flip the door panel over and bend the metal tabs to keep the insert firmly in place.

Pro Tip: Depending on your level of finger callous, you may want to use a flathead screwdriver on the sharp tips.

Step 12: Insert Door Emblem

The door emblems are side specific. Make sure your pony’s running forward, not backward. Secure the pony emblem to the insert with included nuts.

Step 13: Insert Courtesy Light

Like the door emblems, these are side-specific. Make sure the light is facing forward. On the back side of the door panel, secure the courtesy light with its retaining hardware.

Pro Tip: Be careful not to overtighten your retaining hardware, since it can strip easily.

Step 14: Add Molding to Door Panel

Like the insert, these install by flipping up the metal tabs. Push the metal tabs through the corresponding holes. Then bend to secure in place.

Pro Tip: Clean up any loose nylon on the carpeted door section by trimming with a razor blade.
