Ensure the dash in your Fox Body looks factory fresh with this 5.0 Resto 1987-1989 Mustang lower trim panel kit! This trim panel, also known as the "Knee Panel," is usually the victim of holes drilled into it for buttons or switches. Years of removal and reinstallation cause the mounting points to break.


5.0 Resto's trim panel replaces these holes and broken mounting points with a fresh lower dash trim panel. To provide a complete solution, 5.0 Resto includes a new die-cut foam pad in the correct durometer to reduce rattles and replace what's usually missing from the factory panel. This panel arrives in a neutral gray finish that can easily be painted to match your interior. We suggest our selection of 1979-93 Mustang Interior Paint. 5.0 Resto's lower dash trim panel kit is the perfect restoration piece for your Fox Body interior!

Installation Steps


  1. Before installing, you will want to prep and paint the lower dash trim panel. To begin, remove the (2) anti-vibration rubber caps and the (2) metal clips (carefully maneuver back and forth and up to remove, so you do not break the tabs).

  2. 1987-1989 Fox Body Mustang Lower Dash Trim Kit Install - 1987-1989 Fox Body Mustang Lower Dash Trim Kit Install

  3. Thoroughly scuff and clean the panel with soap and water. Once dry, you will need to mask off the trim foam area for paint. We recommend aligning the trim foam first to measure for the correct location.

  5. Spray the backside first with adhesion promoter and apply a thin layer of paint. Let it dry and apply multiple coats within a 5-10 minute waiting period. Do this until satisfied, let the back dry and repeat this process on the front. You'll then want to wait 24 hours for the paint to dry before installing completely.
