The only think I will tell you is that I have the 94/95 MC's on both of my cars that have the Cobra brakes and they work really well. Before I swapped the Coupe over to the Cobra brakes it had the brakes off of a 95 GT on it and that is where the MC came from (although I did get a reman unit and used that one as the core). Brakes were stellar and never had a hard pedal. You can do the math and the 1" MC is hydraulically better but its not by much. With the cost difference between the two and the minimal difference in performance I would just go with the 94-95 unit and go on down the road.
