Ed I have pictures that I can send you of this car it is unrestored and not touched for years.
In the pictures you can see what looks like original door hinges (68 style) top of metal door like 67 interior, 67 dash and I have trim tag picture. You can also see round hole for wiper motor.
That is a 1967 Camaro with a drivers side 68 door cobbled on. Unbolt those hinges and you will find the original 3 hole pattern underneath.
You are correct, it is not restored, but saying that like it's some kind survivor is far from the truth. That car is the opposite of a survivor or restored car. Its a bastardized need everything basket case.
Not worth buying unless you know what you are doing, can do it yourself, and get it cheap, with good title and VIN's/tags.
