thanks man, this is been one of the things keeping me up at night and I really like how it should work. AND If I can get this to work I will do up a detailed list of what I did and how it can be emulated to anyones classic mopar. If it will work the way I want.(this exact plan can be duplicated to a 8 3/4 rear axle by simply adding the same speed sensor to your axles with a speed sensor locked inside the drum. But for my car I'm going to be running the irs out of a charger.
