On the last couple of Pacer fronts we used the disc brake parts were replaced with Ford (nearly a direct interchange) and the A-frame parts work with Chevy 1/2T pickup so no shortage of parts. Ball joints are the screw in Chrysler which took fabbing up sockets. AMC (and International) used parts from other manufacturers to assemble their vehicles so it's just a matter of sleuthing them out. My 65 International 3/4 Crew Cab had Autolite electrical and a C6 automatic while others had Delco Remy electrical and Chrysler Torque Flites.
