Help ID 68 Z-28

[beater68427]

I have found a car here semi local that looks like a 68 Z the engine seems to be the original MO deal 12 bolt rear springs and correct tach, it looks lagit I havent gone to the point of cleaning the block to look at the pad itself, the car is unrestored and paint delete - - - code and looks to be a bronze car Corvette color??? dono??? also a delux interior car, and I think it was a fold down seat?? what are some key things to look for on it other than the norm to decide if it is real, I think it is but you never know. The car is not for sale but could be got in the high teens it does have nos quarters installed and a nos (still black) cowl hood on it that I would remove, incorrect 15 inch wheels but the rest seems good. Just curious if there is some special things I should be looking for that im not aware of.
Thanks Jeff
