Looking at the rear wheel well, in it's race trim, it is cut out to clear the monster slicks. In the latest pic of the car, looks like a normal wheel well opening. Possibly the car was back-halved after a wreck?? Do you know any other history on the car?
At any rate, I get what you are saying. However, it's not like someone recently found an original M code car and hacked the hell out of it. Looks like the original owner bought a factory race car in 1969 and used it for its intended purpose and used it well. Subsequent owners did the same, doing what they either had to or wanted to along the way to keep it alive.
