The story is about the blue car. The silver car is the 302 hemi car in a museum and was mentioned in the article regarding where he got the cross ram parts for the blue car.
The whole story seems a bit embellished to me, but that's what happens over the years I guess.
I don't understand why someone would special order 4 wheel disc brakes and M22 but not 4.11 gears, as he used it mainly for cruising and street racing.
Must have a hell of a paper trail on that car since it was so special to him and he has a picture of him signing the paperwork at the dealer!
