GOD DAMMIT, stop saying this, have you, yourself ever put a set of F-body rims on a GTO? They fit perfectly, the difference in bolt pattern is about the width of a few playing cards. The holes have more play than the difference in bolt pattern. I've ran T/A rims on mine around town and launching at the track with over 550 ft r/w torque on spray, over and over again, well over 100 passes on these rims.
My T/A rims are 8", I don't know if the offset will work with a 9" Camaro rim. Plenty of people have put 10" rims on the back without any modifications, check out the 19" x 10" CCWs, they fit perfectly, saying a 9" rim won't fit is a very broad statement.
So no one can generalize and say they won't fit, try them and let others know. There are plenty of others in the top ET lists for GTOs running F-Body rims.
