GrayInterior:
The interior has been fully restored. The floors were cleaned, painted, and upgraded with a layer of sound-deadening material. New carpets and a Legendary Auto Interiors front and rear upholstery kit were installed. A new headliner has been fitted, though it still requires some adjustment to look its best.
While the dash was removed for restoration, the under-dash A/C components were also restored, including a new evaporator, heater core, and seal kit. A Dakota Digital RTX instrument cluster with GPS was installed, along with an AAR AM/FM/Bluetooth radio and new speakers in the factory locations.
