another wheel and tire fitment thread question

I do not know that measurement off hand, but I have a stock 8 3/4 A body rear end. If both you guys have 3/8 to 1/2 inch of cleareance from the leaf springs, that should be plenty. Thats about what I have as well, but I have never had any rubbing. I would have to look else where for somthing making that noise, ( rubbing sound) Maybe you are rubbing the wheel tub itself with passengers in the car. Your car probably sits a bit lower than mine, as I have superstock springs installed.
