I have bought the Rare Parts brand from O'Reilly's and directly from Rare Parts (I found them via a Google Search on an O'Reilly's part number). They let you into their catalog, even if you are not a registered vendor.
http://www.rareparts.com/I do not know where they are made but they look to be very good quality (original-style tie-rod end).
I used Hotrod's technique for over-boring an axle ( I wish I had known this technique before I guessed it). I used a brake cylinder hone to obtain the final tight fit (and, I froze the pins before installing the pins/assembly).
