I Just Had to use the Heat Wrench to remove the upper ball joints on the 65 Bell. These were definitely replacements. So my question is ... can I feel comfortable Scewing in yet another pair? The arms appear to look fine, however, I take Issue with the threaded area. How much is too much? This will be the third set. Its starting to look a little more chewed up in the bore than I like. Did Ma Mopar have these multiple replacements in mind when they planned the life expectency? Need Input! Thanks Everyone. TL
