Usually a 5.5” backspace is needed to center the 8” wide wheel from side to side on a ‘67 A-body.
I would say you could likely get away with 5” backspace because of the fairly narrow tires you’re planning to use.
I’d get those wheels modified for deeper backspacing or perhaps ask the vendor to do a custom backspace.
A 225/60 is way too small for the rear, a 235/60 would be the minimum size and would be better on a 15x7” wheel which with 4.5” backspace would solve your problem.
A 15x8” wheel would be best used with either a 255 or 275/60, again with enough backspace
