Kelsey Hayes Disk Swap
On my 71 used 73/74 single disk brake still o/e look but 4.5 bbp. req. new lbj,new upper arms and bj,s,reman calipers and new rotors.hoses. the only other thing i ran in to was the sway bar links were longer on the drums than disk links. but if you don,t have a sway bar you won,t have to change them. i did this in 88/89 and could go to the junk yards in fla/ tampa to get parts and with me knowing the parts guys there they rebuild my calipers for me . U.S. brake was there name in ebore city. als
