Ok, picked up some lower front ball joints for our 90 today. 1 is made in Japan and is OEM style seal and looking. the other is made in USA and is thicker around the joint part and is stiffer and has a typical push on dust boot unlike the snap ring japan made one. Both are Moog, and same part number... just 1 is made in USA, 1 in Japan and they are different by means of seal, stiffness and thickness of material in joint area. I'm leaning toward the japan made one... looks like OEM. Any ideas? freakin weird.
