Golden Ferrari, which chassis is the old race body on?

Heretofore I thought it was on 330GT SN8733 the body from the Fellini movie Toby Dammit was put onto and painted red and given a full wise glass windshield.
But then as I looked on the site called Coachbuild
at the many pictures
of a 250GTE# NART spyder SN2235


Fantuzzi Ferrari 250 GTE NART Spyder #2235GT 1961

it seems to be the same body shape as the Golden Ferrari, minus the side vents and rear fender side vents of the golden car in the movie. Anybody know the origin of the body on the NART spyder other than being by Fantuzzi?

 

..over the Golden Ferrari side view. It looks a little taller

Fantuzzi Ferrari 250 GTE NART Spyder #2235GT 1961

in this side view and the side vents on the front fender are different
and the windshield is taller
the rear fender side vents are missing
but otherwise it looks the same.
But now I have to check the NART 350GTE history I think it was already existant when the golden Ferrari was made.
That idea of laying a transparent overlay picture atop another picture of the car came to me from a guy who bought an early barchetta and discovered it was a LeMans racer by laying a transparent picture over the LeMans race picture and found the body with its unique hood scoop was the same
