Will new style Pontiac GTO rims fit third gen?
According to the Ronal chart here:
http://www.ronalusa.com/cars.html
our bolt pattern is 5 x 120.65, and the GTO wheels are 5 x 120
is half a millimeter going to make a difference?
Thanks in advance!

Thanks! They seem to be plentiful and cheap, since folks are taking them off their GTO's to put on aftermarkets. Do ya have any info on how much spacer is necessary?
They are pretty sharp wheels, and 17":

From what i've found they are a 6.15" backspace wheel, if this is the case I would run a 1" adapter, order them with 5x4.75(120.65MM) on the holes and 5x100 on the studs and I believe getting them from skulte which I would suggest you can get them with a centering ring step, get this in 69.6MM dia

Could you post a pic once you get those on. I'm curious to see them on a 3rd gen.

that .65mm difference in bolt circle is just enough to cause problems. I know that some people around here have done the same with bmw wheels (same bolt circle), but I wouldn't do it.

that .65mm will only cause the 5 bolt holes to be close to the inner surface. That is .13~mm per circle... You know how the wheels have the spacing around the stud? That is usually about .24mm (i was bored and measured three cars 
) They would be fine.

these wheels also require a smaller centering ring. i tried to bolt them on my forme and the back ones are all that would bolt up, and that was finger tight cause the centering ring was bigger than the wheel had. also, i mesured the gap between the wheel and the drum and it was an inch gap, plus atleast another inch to get the wheel out far enough. the fronts wouldn't bolt up do to the wheel hitting the rotor/caliper, and i ruff mesured by holding the wheel up by hand and used a tape mesure and found what looked like a 2" spacer was needed, mabee more. i could be wrong but that is what the tape mesure said.
thanks
