With flares... 10" minimum. I run 9.5" rear wheels with no flares on my '71. If I had another 2" to work with, I'd be using all of it. 
FWIW, I run 4.9" backspacing and the only modification is the e-brake cable bracket has been moved to the top of the stock trailing arm. I run 8.5" wide on the front with 4.5" backspacing.

Yes, those will easily clear the e-brake with no modification. 4" BS means they will stick further out, not in, so you will be fine with inside clearance. I don't know how wide your flares are and if you want the wheel/tire tucked inside or not. That would be the next question for you... and only you can take the measurements to see.
