I have a 1972 dart swinger that has the 10 inch drums all the way around. I have bought a very nice kelsey hayes 4 piston setup that came from a 1970 dart 340 and have been wanting to install them for years but am unclear on some things. Can i keep my upper and lower control arms or does one of them need to be changed in order to use the K-H disc setup? I have read that the upper arms has to be changed and i have also read its a direct bolt on...HELP!!
