Front vs. rear track width

so i'm just curious....... when you say your front is 2" wider do you mean per side or overall? i just measured mine (approx) and my rear end is about 4" narrower overall than my front end, 2" per side. i have an 8 1/4 rear end on a 70 dart that is more or less a peiced together frankenstein car. just wondering if my measurements are inline with what you guys are discussing.
