For those of you who aren’t familiar with what this car is, its the 240ZG or the G-Nose.. Here is the wikipedia explanation of this model, an accurate explanation at that.
The HS30-H Nissan Fairlady 240ZG was released in Japan in October 1971 to homologate the 240Z for Group 4 racing. Differences between the 240ZG and an export market Datsun 240Z include an extended fiberglass ‘aero-dyna’ nose, wider over-fenders riveted to the body, a rear spoiler, acrylic glass headlight covers and fender mounted rear view mirrors. The 240ZG was available in three colours: Grande Prix Red, Grande Prix White and Grande Prix Maroon. The “G” in 240ZG stands for “Grande.” Although the ZG was never sold outside Japan, in order for it to be eligible for competition in the U.S., Nissan sold the nose kit as a dealer’s option which is known as the “G-nose”.
In the words of the Notorious B.I.G. “and if you don’t know, now you know, *****!”
By the way, just because your S30 has headlight covers on it DOES NOT make it a G-Nose!

To this day, one of my absolutely favorite all time cars….an S30 with the G Nose. Everytime I see one, I am reminded of why I love my Datsun so much!
