I have taken pictures of the fuel line, which is single, with a tape measure next to it. It is a real SS, it has the paint code 72 (on the Trim Tag), which is Monaco Orange, which could only be had on an SS in '69. It did not come with air conditioning. It only has idiot lights on the dash. It is a 4 speed car, bucket seat, no console, standard steering wheel, built in Atlanta. It does not have the original motor and I have not found any build sheets. The last place I can look for that is on top of the gas tank, which looks to be original, but I am not holding out much hope. Anything else I can look at to determine whether it is an L78?
