All of the equipment you describe the car as having are easy to add. The vin # will only tell you if it was a six cylinder or a V8 when it left the factory. The trim tag on a 68 is also of little value as it only gives color and trim information. The best way to verify the car is check the engine pad to see if the original stamp is still there. If it is a MS code engine than it is probably original to the car and would verify it's a SS350. Check the transmission on the passenger side for a vin # that matches the car. The 308 12 bolt rear would have been a normal rear to find in a SS350 so you should check the code and build date on the right side axle tube. The speedometer cable on a Muncie trans (which all SS 4 speed cars came with)should exit the firewall on the right side of the steering column unlike a Saginaw trans which would have gone to left of the column. Check the tire decal on the glove box door. If it is still there is should have F70 X 14 size tires.
