Jon;
Not sure what you mean by "Corvette" box from A & C.
In the pedal box that Pete Clark (Fast Times Rods) made for me he put a Corvette Master cylinder on it for me.
If you get the Ron Francis or American Auto Wire Wiring harness it comes with a brake switch you plum in the brake line coming out of the master cylinder. Very easy, very clean. If you are thinking of a switch that the foot brake pedal comes in contact with when depressed. Can't help you, sounds too complicated.
