In addition to the LT1, the ZR1 package included a manual M22 Rock Crusher 4-speed heavy-duty transmission, J56 heavy-duty power brakes, J50 power brakes, transistorized ignition and special heavy-duty aluminum radiator. The F41 heavy-duty suspension included special springs, shocks and front and rear sway bars. This car is dressed in Pewter Silver over Saddle interior. It was purchased new by Albert Stephan from Rosenthal Chevrolet in Arlington, VA. A three-owner car, it is loaded with original documentation including the original Virginia title, Protect-O-Plate, Tank Sticker and inspection receipts which document its mileage. This car was purchased by a significant collector from the original owner. This ZR1 was then treated to world-renown Kevin Mackay of Corvette repair to undergo a complete frame-off restoration.
