it is always alot better to get a disc brake set up from the same kind of a car you are installing it on.that way you know the parts will fit without modification and you know what to ask for at the parts house later on when repair work is necessary.sounds like you got the wrong parts.you will also need the 3 proportioning valves to do the job right.if you need the right parts.i have them.youjincho@prodigy.net.954-721-1459
