Default 18 inch wheel fitment, '67 LeMans/GTO?

So what is the ideal wheel width and backspace to fit about a 255/45/18 tire in the rear wheelhouse of a '67 LeMans? I'm considering going to 18" wheels to fit the C5 brakes on the AFX spindle. The issue is most 18" wheels have 4.5" of backspace, which may not be deep enough to fit most wide tires.

I really like the US Mags Bandit 109, but they only have 4.5" of backspace. Is that going to tuck a big tire (at least a 255) under a 67 GTO/Lemans with 60" axle?
