Another Wheel & Tire Fitment question

I own a 72 240z with Tokico HP struts & springs and I'm interested in buying the Sport MAX 16 x 8 Wheels now on the Motorsport website (see attached). They are saying they will fit with no mods but several of my fellow Ontario Z Club members say I will need to modify the spring seat and maybe the fenders.

Has anyone bought these wheels for a 72', and what was your experience?

Thanks
