I was trying to put disc brakes on my 1969 El Camino and I was told by a mechanic that the easiest way to this and save some money was to get the caliper, rotor, upper/lower control arm, and the coil-over-spring assembly from a 1991 Chevrolet Caprice because it would mount up and the only thing that doesn't fit is the upper control arm mounting bracket because the holes are to close together and i was wondering if anyone had a quick fix idea?
