All things considered I would prefer the Scarebird kit over the eci kit. Here's why. On the eci kit it uses gm parts for the rotors, and calipers. Its also whats considered a slip on rotor the wheel hub is a separate piece retained by the spindle. What I like about the scarebird setup is that it uses a 1 piece rotor much like what 73 c-bodys use where the wheel studs are built into the rotor. It uses Ford full-size 1970-1972 11" rotors, and dodge 1995-1999 1500 1/2 truck front calipers. I think it's a better built kit. for 165 you get the brackets, you have a choice of what quality of rotors you buy since you source your own, and bearings ect. You do need a disc brake master, and for maximum stopping power you should step up to a dual diaphragm disc brake booster. I know some people have gotten away with using the drum booster.............. in a panic stop it doesn't have the capacity to lock the calipers down. I have a friend who runs the eci kit on all 4 wheels on his 68 fury. In order to run the rear disc brakes you need to use the non adjustable green bearings. Just my 2 cents.
