Aerospace front/ Explorer rear, what MC?

[codycr6]

I am putting Aerospace front discs on my 1964 Ford Fairlane, and swapping in a 8.8 inch rear out of an Explorer. The rear came factory with 31 spline axles, limited slip, disc brakes, over-ride traction bars, and a locater bar to keep the rear centered. I was planning on using a master cylinder for an Explorer as well, since it is four wheel disc. What other considerations do I need to make up front? I am going to wait until after it is together and tested before I add a proportioning valve. I am usually working on race cars, and we use a lot of Aerospace brakes, but this is the first combo like this I have done. We thought we would use the Explorer master cylinder first, as it looks like it will bolt in, and is fairly inexpensive.
