If it is car 350 than the red DAN ARENA pict is not correct.[-x
However I think it is indeed The same car thus it can not be #350 as that should be Bill Collins car.
It just is so funny to see a Karmann back window in a Heb, I have this late 50's pict of a Ivory or white heb( black and white pict) where you can clearly see that they used also a Karmann back window. I wonder if it is the same car?
I will ask Dan if he can clear this out.
I am pretty sure that Dan Arena's car is without a Heb number in the front.
