Damn, you beat me to it. Just got home from Joe Darlington's place, picked up the RS and my diff drop brackets. He said pretty much same thing, you might get 1/2 to 3/4". Not worth it. He is willing to make more diff drop brackets, Iam sending him mine as cores. 200 bucks for the brackets, another 100 if you don't want to mod your own cross member. Shoot me a PM if interested.
