I was thinking about adding a disc brake setup to my 1956 pontiac. i seen theres many kits out there..'the 2 most common I've seen 2 types. the one type where you repalce spindels and get all the hardware.the other you can use the standard spindels and get the hardware.... I also been told you can use a spindel off an older chevy fullsize van and you can use all the components i dont know if this is true or not and what year???
