1999-2004 Ford Mustang Vertical Door Kit | VDI VDCFM9904

1999-2004 Ford Mustang Vertical Door Conversion Kit

Vertical Doors, Inc. VDCFM9904 is a vehicle-specific vertical door conversion kit designed for the 1999-2004 Ford Mustang. The kit retains the factory front doors while changing their movement so they open outward first and then raise vertically.

Also commonly called a Mustang Lambo door kit, scissor door kit, or vertical door kit, the VDCFM9904 is designed specifically for the New Edge Ford Mustang and its SN95 platform.

Give Your New Edge Mustang the Lambo Door Look

The 1999-2004 Mustang is known for its distinctive New Edge styling, with sharper body lines, sculpted quarter panels and the long front doors characteristic of the SN95 platform.

A vertical door conversion puts those long factory doors on display with a dramatic upward-opening motion while retaining the original door shells, glass, interior panels and factory body shape.

The VDCFM9904 Ford Mustang vertical door kit uses vehicle-specific hinge assemblies rather than a universal weld-on conversion.

VDCFM9904 Product Specifications

What's Included With the VDCFM9904 Kit?

• One driver-side Vertical Doors, Inc. hinge assembly
• One passenger-side Vertical Doors, Inc. hinge assembly
• Two gas shocks
• Required mounting hardware
• Vehicle-specific installation instructions

The kit is designed to retain the Mustang's original front doors. The VDI hinge assemblies and gas shocks provide the hardware needed to change the doors to vertical operation.

How Does the Mustang Vertical Door Kit Work?

After installation, each converted front door initially opens outward like a conventional door. Once it reaches the hinge system's stopping point, the door can then be raised vertically.

The included gas shocks assist with the upward movement. Proper installation and adjustment are important for smooth operation, correct door alignment and adequate clearance around the door, fender and surrounding body panels.

Installation Requirements

The VDCFM9904 is designed around the Mustang's factory hinge area. While the vehicle-specific design provides dedicated mounting hardware, bolt-on does not mean modification-free.

Installation commonly requires careful body-panel removal, clearance work, wiring management, hinge adjustment and final door alignment.

Typical installation procedures may include:

• Removing the front fenders to access the factory hinge area
• Removing the door panels to access the door wiring
• Creating additional wiring slack where necessary
• Routing the wiring through the modified hinge area
• Cutting the factory wire boot in half for routing
• Non-visible inner-fender trimming for necessary clearance
• Installing and adjusting the VDI hinge assemblies
• Installing the gas shocks
• Final door alignment and clearance adjustment

The factory wires generally do not need to be cut; however, wiring must be properly routed and secured to prevent interference or damage during door operation.

Protect Your Factory Door Alignment

Before loosening or removing the original hinges, use 2-inch painter's tape to mark the factory door alignment. Place tape across the door and adjacent body panels at several reference points, including areas near the hinges and firewall. Draw matching alignment lines across the tape.

These reference marks can help restore the door to its original horizontal and vertical position during reassembly and adjustment.

If you are not experienced with automotive body-panel removal, door alignment, trimming, drilling or tapping where applicable, or wiring clearance, professional installation by a qualified automotive customization or body shop is recommended.

1999-2004 Mustang Fitment

The VDCFM9904 is listed for the 1999-2004 Ford Mustang and is intended for the fourth-generation New Edge Mustang on the SN95 platform.

Mustang configurations during these model years included models such as the V6, GT, Bullitt, Mach 1 and SVT Cobra. However, the trim name alone should not be used as the sole basis for fitment.

Confirm the exact model year, model, body style and door configuration before ordering.

Vehicles equipped with aftermarket fenders, widebody kits, Cobra or Mach 1 body modifications, custom bodywork, previous collision repair, replacement hinges or modifications around the hinge and fender area may require additional consideration before installation.

Coupe vs. Convertible Fitment

The 1999-2004 Mustang was offered in both coupe and convertible configurations. Because vertical door hardware is vehicle-specific, confirm the exact body style of your Mustang before ordering.

Do not assume that a kit for one Mustang body configuration automatically applies to another vehicle simply because both vehicles share the same generation or model-year range.
