This performance coupe received a top-to-bottom refresh that encompassed body and paint work, a modernized interior, 18” aluminum wheels, a disc braking system, and an overhauled suspension. Motor upgrades include performance headers, an aluminum radiator, an Edelbrock intake, and a custom 3” exhaust system, with power sent to the ground via a positraction Dana 60 rear end.

The Road Runner mid-size performance car launched in 1968, and two years later the body received a new grille, hood, fenders, and quarter panels as part of mid-cycle refresh. This Road Runner from 1970 has an RM21 pillared coupe body style and underwent a complete overhaul within the past eight years under the seller’s ownership, receiving a motor, transmission, and restoration. Previously, the car was held in long-term indoor storage since 1990. The body was stripped to bare metal and some areas received new sheetmetal including the lower rear quarters, trunk pan, and lower rear window quarters. The Rallye Red exterior has matte black accents and received a reseal with two-part urethane sealant as well as an epoxy base primer and a urethane top coat. Brightwork including the bumpers, vent window frames, and other trim accents were rechromed. Finally, the interior and exterior seals were replaced.

Aluminum 18” five-spoke American Racing wheels with polished lips are wrapped in Nitto tires with 2015 date codes that have been driven fewer than 3,000 miles. The suspension was overhauled using Moog front components, reinforced lower control arms, and Firm Feel upper control arms. At the rear, handling is provided by new leaf springs with AR Engineering hanger brackets. The braking system was upgraded to stainless-steel lines, front discs with Disc-O-Tech components, and a rebuilt Bendix double-diaphragm and a CVR electric vacuum pump for the brake booster. The power steering gear box was rebuilt as well.

The all-black interior was converted from the original bench seat, column-shift configuration to bucket seats with a floor shifter, along with complete refurbishment of the re-padded upholstery, door panels, headliner, carpeting, and embroidered floor mats. A three-point seatbelt system was integrated both front and rear, and additional amenities include a Vintage Air A/C system, a B&M floor shifter using the original shifter linkage, and a RetroSound radio. The trunk contains a relocated Odyssey gel battery with a billet tray and quick-disconnect.
