1979 corvette help

[D.O.M.D1]

I need some help in identifying an old corvette that popped out in one of my local dealers and its hard to find solid evidence on what the car has and the thing is it does not have a 17-digit VIN(pre-1981).Frankly I don't know if the transmission is the 3-speed or 4-speed automatic.

I have no idea if this car is a rare gem or a diamond a dozen
