Well ended up buying the duralasts. I asked the clerk who makes their suspension parts, namely these tie rods and he said Moog makes them for AZ in their boxes. I compared the originals and the new ones...new ones look heftier than original 63 stuff and with a lifetime warranty, I'll take the chance considering the car only gets driven maybe 500 miles a year they should last as long as originals. Thanks for all the input.
