At the time I was knowledgeable enough to know what it was but not enough to take pictures (Brownie Instamatic) or look for serial numbers. So to me, the number is moot.
I know I saw Kolb driving a gold 427 up Broadway, his tie flying in the wind. My reaction was that the car was so quiet. In NYC (Manhattan) everything is amplified by the echos off the buildings which act as canyon effect.
Considering that it was totally unexpected and other then it being a bikini go-go girl who lost her top, this would be just as great...ah, almost as good. In other words, it just made my day.
Normally in either case, I would have been chased away and told, "get away kid!", and I didn't even get slapped.
