I`m almost sure camaro and nova from 70 to 80 are the same, the buick is the same as far as width from eye to eye, they are just 2 inches shorter in lenght, only the G bodies like the 80 to 89 regal. Just take a tape measure with you and your measurements to be sure, you`ll have to get everything a-arms and splindles, calipers and brackets, you`ll have to use the 70 camaro tie rod link adjusters they are longer and stepped if I remember, we did this same on a `55 chevy some years ago, same issue the nova was to wide,( after it was welded in ) a well informed wrecking yard guy gave us this tip, then we was good to go.
