Ball Joints are in AMC/Jeep box. Part number was 8121792 which was superseded by 8122629 and on and on. One kit does one side upper and lower. One kit is missing the lower nut and the upper adjusting socket. They have no markings as to where they were mfg either on the ball joint or the boxes. I think I have the ,missing parts (used) but so will you. If interested I'll take $50.00 for both kits plus postage.
