Default 73 engine pad anomaly

I have been looking for this photo for a number of years; I finally located it.

This is the VIN derivative stamped on the engine pad of a 73 base motor convertible that I used to own.

The correct VIN of the car is 1Z67J3S422397. That VIN is clear on the engine pad.

But notice the last digit.

The engine pad (and the transmisssion as well) were originally stamped 13S422398. Then the last digit of the VIN was changed from an '8' to a '7'.

Just another interesting engine pad anomaly.

FYI: The car still exists, and is driving on the streets of Huntsville, AL.

Actually, it appears that the pad has been completely restamped. You can see faint impressions of the prior stamping underneath the present numbers. Perhaps this is an anomaly of the digital photo, lighting, and presentation on a computer display. But, I think not.

Whether this was done by the factory (engine repair after failing final test?) or later in an attempt to deceive, there is no way to know.

I wasn't sure about that, and it has been almost 20 years since I owned this car.

But I think I recall thinking that just the last digit had been changed. Of course if it was done carefully enough, it would be almost undetectable (which it is).

I'd say it was a factory restamp.

I actually call it a factory overstamp.

I always wondered what the engine pad for #22398 looked like.
