How many inches or mm does a stock 1970 Pontiac Lemans have in front & rear? ?

I read that people have 6" backspace then I read 5.5(rear) and 4.5" (front) is the magic #. So my 18"x9.5" rims(275/40zr/18) have a rear offset of 65mm. That would mean I need a 2.5" wheel spacer. My front rims are 17"x8.5" (245/45zr/17) with a 58mm offset. So I'd need a 2"wheel spacer in the front.

 Is this correct math ?

    NEVER use offset rims and wheel spacers kid

    You will merely destroy suspension components and bearings faster and if the tires stick out past the fender you just made the car illegal to drive o the road
