Topped off with correct Winters snowflake intake, correct tri-power setup and ignition shielding. The body on this curvaceous Corvette is impeccable with tight lines and and mirror finish black paint as well as newer chrome. According to the previous owners this car was a no hit car with bonding strips intact before starting the restoration process. The trim tag was judged and validated as being a true black car with black interior making it even more desirable. The interior was also restored during the extensive restoration process and shows very well with wear free bucket seats, clear crisp gauges, topped off with a black soft top and matching black hard top. This car came from a high end collection where it was driven very sparingly, stored in climate controlled environment and kept on jack stands to avoid flat spots on the tires. Less than 1200 babied miles driven since the frame-off restoration. The blue chip muscle car retains its original M-21 close ratio 4-speed transmission backed up by its heavy duty posi-traction rear end and power disc brakes to control the power. Rolling on correct Corvette rally rims and redline tires for that pedigree look.
