Scarbird vs. Old daddy ( Rusty Hope) vs. Aj vs. Eci brakes, ? Which and why. Prices very near to each other. One doesn't have web site and doesn't use computers. Little bit scary! I will entertain all thoughts , recommendations and input from all. Thanks. Will spend money once narrowed down. Some say drill and tap spindle, some say not needed? Some say have to measure dia. of spindle some say no.
