coil without ballst resistor?

On my 440 dart, i switched out the stock mopar ECU box for the GM 4 pin module and have it hidden inside the old mopar ECU box to make it look original, but am using the GM coil also. No longer need the ballast resistor which i like. I dont care for the look of the square GM coil though and want to find a cylindrical shaped coil that looks somewhat like the original one that the mopar ignition used but i need one that will work with the GM module and does NOT need a ballast resistor. Anyone know of coils that dont need the ballsat resistor but look like the old original coils?
Thanks!
