i have`nt been here in a day or two and it took me forever to find how to open a thread .. i looked and found plenty of threads about ball joints but could not open any .. anyway can someone tell me the difference between 73 ball joints and later ones ,, the only thing i can see is the bolt holes are a few thousands off . i have both on hand .. believe me i can open up a bolt hole on a 27 $ 1975 ball joint easy enuff to keep from paying 127 $ for a 1973 ball joint ...
