I put Iroc wheels on my 1981 Z28 years ago. I had to put the front on the rear and use wheel spacers with longer studs to get clearance on the control arms. It still required some work. I tried them on my 69 one time and it was even farther from fitting. I am certain you can make them work with some effort, but it will not be a direct bolt on because of the big difference in wheel offset or backspacing depending on what you want to call it. Good luck.
