Rotor application problems

[SpeedyV10]

Hey everybody,

I am really hoping that I can get some help on this! Okay- so here's the deal:

I bought a stock style power disc brake conversion kit for the '61 Impy. It uses what I believe to be GM intermediate rotors and calipers, and is bolted to the stock Impala spindles with the help of a bracket.

The problem is, the rotor pushes the front wheels out too far. The disc has a 1 inch thickness, and the 'hat' or center of the rotor is 2.5 inches thick. When you turn the wheel sharp, the tires will definately hit the fenders. Unfortunately changing wheel offset will not help as the car is extremely low.

Is there another GM rotor that has a shorter 'hat' and offer the same bearing spacing?

Help!!!!
