only on the front of the tta.
The reason you see the stamping "front only" on the backside of the mesh pattern, such as in your pic #10, is because the GnX wheel IS the same wheel as the Pontiac Trans Am used on the front, it wasn't special manufactured. (Trans am rears had a different backspacing, thus the wheels when cast were stamped "front only" and "rear only" so it would be known where to mount on the Trans Am/GTA cars ordered with the 16" mesh wheel option in either black or gold.
The only two things that make the "GnX" wheel "unique" from the tens, likely hundred thousand trans am/GTA units produced through the years are the production date and the the fact that early versus late wheels were differentiated by the lack or presence of dimples near the center cap hole in the mesh grid.
That's why you will see mention of "dimpled" vs "non-dimpled" for those who are looking at the rims.
So.... are they harder to find as time goes by with the correct date/casting window? Yes.
But are there likely at least 5000-10000 potential wheels out there that can be Gnx correct if every front wheel of the correct casting range was rounded up and refinished in black? Also yes.
