You know I'm still confused on this wheel thing. At the GM Nationals, the guys that built that chevelle look-a-like out of a 04 GTO had some really nice billet chevelle wheels on the car. I asked them did they have them custom made for the bolt pattern. The owners told me that they were the standard GM bolt pattern of 4.75. I'm still confused.
The 4.75 pattern will fit because its 120.65mm, vs the correct bolt circle is 120mm.
You can bolt them on and they will bolt up, but if you look closely, your lugs will not be centered in the holes on the 4.75 and eventually, you could have lug failures.
No way will i put 5x4.75 wheels on my ride. I went through that with the GTP and the AE077s at 5x4.5(114.3) versus the 5x115 they should have been. I lost at least one stud on every wheel. I think 2 or 3 on one wheel. Never again.
