I have a 72 Iron Pig the I learned had 1 bad tie rod on the left side. Would anyone recommend that I replace all of them or just the one? Granted all the boots look like the third ring of hell, bu there is no movement in other than the left front. My other issue is where do I find tie rods worth putting on the vehicle? I have looked on SOR and they are way to proud of them. Thanks for all the help
