1968 Chevrolet Corvette description

Up for sale is an unrestored 1968 Corvette Convertible with numbers matching 427 engine and manual transmission. I purchased it from the owner of the last 30 years. I intended to do a restoration project on it, but just don't have the time. It appears to be all there and ready for a restoration. The 427 engine is out of the car and has been for some time. The prior owner removed it to restore it and put a 1970 corvette 350 in its place. It is currently in the vehicle and turns freely. It goes with the car. The 427 engine was taken apart and cleaned, with all parts there, but not put back together.
I am readily available to answer questions and show the vehicle. It is currently located in my garage in Morgantown, West Virginia.
"Corvette '68... all different all over". That's the quote from the sales brochure for the redesigned 1968 Corvette. The body was completely redesigned with the coupe losing it's fastback window but gaining a removable back window and removable t-tops for that almost convertible feel. The chassis itself did not change much from the 1967 model. The new hidden wipers and hidden headlights are vacuum operated instead of electrical. Door openers now use a push button to open and a push in handle to pull the door, this was only used on the 1968 model. The new auxilliary top for the convertible has a glass rear window. The new standard automatic was the 3-speed Turbo Hydra-Matic instead of the 2-speed PowerGlide used previously. A new fiber-optic monitoring system was added to the dash and "Astro-Ventilation" was added to improve the airflow in the cabin. The '68 Vette did not have the "Sting Ray" badging on it anywhere, it would return in '69 as "Stingray". 1968 was also the year that Zora Arkus-Duntov was named Chief Engineer of the Corvette.
