16x8 +20 on a 78 datsun 280z will these fit?

[Zzzz]

hi guys, 

wondering if anyone of you know if these wheel specs will fit on a 78 datsun 280z with no modifications.

 

16x8 zero offset in the rear

16x8 +20 off set in the front

 

tires are 195/45/16

 

they are xxr 531's 

 

here is a pic of my car i just picked it up not too long ago.

rears will, fronts will most likely rub w/o spacers. That's a crazy wheel size. 45's might look ok.
