I have 14x7's with 3.5" of backspacing on my 67. So my wheel sticks out 3.5" from the center, right? Your wheel sticks out 4.3125" from the same center point making your wheel stick out towards the fender lip .8125" more than mine do. My tires rubbed before I rolled the fenders. Of course, your tire size will have a huge affect on this also. I have 235/60R14's, fairly wide tires. My guess is you will be running a 245 series or more. From my deduction, it will rub, a lot.
