Im going to be putting disc brakes on a 72 dart i just bought.I cant seemed to decide which route to go,WILWOOD DISC BRAKE kit or go with the scarebird conversion.I want to stay with the small bolt pattern front wheels,Centerline 15x3 or 15x4s,not sure which width.It seems like the scare bird kit would be alot cheaper,but that worries me alittle.Any thoughts?
