Welcome. I'd find a new mechanic if yours doesn't have the basic common sense or background to do a few minutes worth of digging to determine what you asked here.
to from Atlantic Canada! I have added your VIN to our VIN Sequence Thread Can you confirm your ignition switch (key) is located on the steering column? Your VIN currently looks like one of the earlest Kansas-built cars we have on our List. If your ignition switch is on the dash, then it is a really late 69.5 car. Is your door sticker intact? What date is on it?
